Internet of Things – A Future Thing

Of all the technology buzz that are trending right now, perhaps the biggest one out of all is the Internet of Things. It is the one that’s going to give us the most disruption as well as the most opportunity over the coming decade, it could completely transform our way of living in future. The concept of Internet of Things first became popular in 1999 and since then this buzzword has been floating around and experts estimate that the LoT(Internet of Things) will consist of almost 50 billion objects by 2020, but what does it actually mean, what does Internet of Things mean?

Here’s something about it:

Internet of Thing is about connecting devices over the internet, letting them communicate with us, with other devices and applications via a network. It refers to the ever-growing network of physical objects that feature an IP address for internet connectivity, and the communication that occurs between these objects and other Internet-enabled devices and systems. It revolves around increased machine-to-machine communication; it’s built on cloud computing and networks of data-gathering sensors; it could make everything in our lives from household appliances to highways, from streetlights to seaports “smart.” In a nutshell, Internet of Things is based on sensors, cloud computing and a network(or internet-enabled devices).

Let’s talk about a very few examples of the Internet of Things:

Home’s light control system integrated with sensors to switch off/on the lights depending on whether there’s anyone in a room or not, alerting you of any suspicious activity on your phone and make it possible to switch off/on lights remotely; windows and doors fitted with sensor and could detect of windows and doors openings and violations to prevent intruders, and alert you of the same by texting on your number; informing you about running appliances when you are not at home, and allowing you to switch on/off remotely to save energy or to avoid accidents. A smart fridge which could text you if its internal cameras find there is none left, or that the carton has past its use-by date; energy and water supply consumption monitoring by sensors and applications to suggest/advice you how to save cost and resources.

LoT  or Internet of Thing is more than smart appliances and smart homes. It scales up to include smart cities, think of connected traffic signals that monitor utility use, or smart bins that signal when they need to be emptied, and industry with connected sensors for everything from tracking parts to monitoring crops. Constructing smart building, bridges, highways, use of smart cement equipped with sensors to monitor stresses, cracks, and alerts you to fix problems before they cause a catastrophe. If there’s congestion/damage on road, the same sensors in the concrete will detect it and communicate the information via the wireless internet to your car or on your phone to alert you.

It has limitless applications and potential, and of course there are some concerns too. This technology is full of possibilities and it’s often difficult to decide in early stage what it will bring up in coming years and will it be truly ground breaking or not.

Here’s a video on it by Intel:

Bringing Texture to Your Flat Touchscreen

It could be possible in future we could feel the texture on touchscreens. Scientists have taken a closer look at bringing texture to touchscreens and have found that under circumstances, people can feel “virtual bumps.”

Here’s something which has been published on this research:

Northwestern University and Carnegie Mellon University researchers reported a fascinating discovery that provides insight into how the brain makes sense of data from fingers. In a study of people drawing their fingers over a flat surface that has two “virtual bumps,” the research team is the first to find that, under certain circumstances, the subjects feel only one bump when there really are two. Better yet, the researchers can explain why the brain comes to this conclusion. Forces felt by the fingers as they travel along a flat surface can lead to the illusion that the surface actually contains bumps. This “virtual bump illusion” is known in the haptics field. Intrigued by this phenomenon, the scientists decided to make use of it.

By leveraging the virtual bump illusion, we were able to design a meaningful experiment that shed light on the way the brain integrates information from multiple fingers,” said Colgate. “Our big finding was ‘collapse’-the idea that separate bumps felt in separate fingers are nonetheless experienced as one bump if their separation happens to match that of the fingers.”

The researchers presented two virtual bumps with the use of haptic technology, with the distance between them varying across trials, to volunteers. When bump and finger spacing were identical, the volunteers said that they felt the two bumps as one. “Our findings will help us and other researchers figure out how to design haptic technology to produce certain tactile effects,” said Michael Peshkin, one of the researchers. “Haptics-giving a feel to objects-just enhances the physicality of a person’s experience.”

This new research and its experimental results on “haptic illusions” could one day lead to flat-screen displays featuring active touch-back technology, we could in future see screens where you can feel certain components, such as making your touchscreen’s keyboard actually feel like a keyboard.

Kilobots form Synchronised, Complex Shapes

Recently a report came up on 14 Augsut’14 which says Harvard researchers have designed a swarm of small, mobile robots which are able to organize themselves into large shapes from random starting points with minimal initial human assistance. This technology is in research from few years, and referred as “Kilobots”.

The Kilobots are a team of 1,024(210 being a conveniently binary number) simple robots that operate as a collective to complete the assigned task, much like the Borg in Star Trek or termites in a termite mound, and been shown to demonstrate the ability to swarm together to form complex shapes like the letter “K”, or a starfish. The researcher team at Harvard first introduced their Kilobots in 2011, and this time they have built one thousand of it. The research is another step in the development of artificially intelligent self-organising systems that will affect everyday life in the future.

Each robot can bounce an infrared signal off the ground to another bot beside it, allowing it to sense where it is in relation to others in the swarm. Bouncing that signal can also ensure that one’s robotic neighbors are on the same page for when and how a task is supposed to be carried out . Knowing where other robots are is essential when it comes to locating objects in a given environment and bringing them back to the home base.

Professor Radhika Nagpal (from Harvard School of Engineering and applied Sciences) said: Increasingly, we’re going to see large numbers of robots working together, whether its hundreds of robots co-operating to achieve environmental clean up or a quick disaster response, or millions of self-driving cars on our highways. Understanding how to design ‘good’ systems at that scale will be critical.

The results of the experiment are published in the journal Science.

Charging Phones Using Everyday Noise

Charging Mobile Phones using soundMobile phones may someday be able to recharge using the sounds around them. This can be possible with the help of piezoelectric property of zinc oxide, when the zinc oxide nano-rods are squashed, stretched or bent, they produce a voltage. The nano-rods can be coated onto various surfaces in different locations making the energy harvesting quite versatile. The zinc oxide nano-rods respond to vibration and movement created by everyday sound, such as our voices too. Researchers are working on it from many years to design a nanogenerator which can be used to power devices like mobile phones and now they somewhat succeeded in it.

Few years ago, a few Korean scientists had proposed using sound to charge mobile phones. They explained that it could be done by utilizing piezoelectric effect, in which zinc oxide nano-wires converted sound-caused vibrations into electricity. At the time, the researchers couldn’t generate enough of a voltage to actually charge a phone. But now as per recent research, scientists from Nokia and Queen Mary University of London have succeeded in doing so.

Scientists from Queen Mary University of London and researchers at Nokia built a mobile device that can be refueled when everyday background noise, including traffic and music, is converted into electricity. In future, it could be possible to charge mobile phones using everyday background noise such as traffic, music, cheers from a football field or chatter from a coffee shop and our own voices.

Scientists are now able to generate five volts by using this method, which is enough to charge a phone. Certainly, this technology can change the way we charge our devices if it will make its way to the smartphone industry. It’s still a thing of future and matter of research so far.

Truth is Beyond and Hidden

Things can be defined in possibly infinite ways, we may presume things differently based on what our mind and heart agrees to. The things which I find real might not be real to you, reality is individualistic. How a person sees things and perceives them is a matter of wisdom, knowledge and experiences. Universe is all about vibrations, frequencies and energies, and we all are part of it and everything is. A stone is really a stone or is just a transformation of energy in the form of stone and alignment of some billions of atoms vibrating at some frequencies at some energy levels? Actually, the thing is things are different at atomic level from what we see through our eyes.

Once Nikola Tesla said “If you want to find the secrets of the universe, think in terms of energy, frequency and vibration”

Everything is made up of atoms, and the same atoms vibrating at different frequencies, at different energy levels make things solid, liquid, gas or invisible. All in all, actually this leads to a conclusion that everything is same and one when we think in term of vibration, frequency and energy, vibrating at different frequencies at different energy level. State of matter is not truth, truth is beyond and hidden. Truth is beyond from what we see and feel, it’s about vibration, frequency and energy.

PlanTree – Solution to Grow Organic Food at Home

There is an interesting concept and solution to grow organic food at home designed by Nur Yıldırım, and it is called PlanTree. The PlanTree is an interesting solution to allow people to grow all sorts of herbs, fruits and vegetables within their very own homes.PlanTree-Eco Technology1

Here’s what Nur Yıldırım says about his PlanTree:

Designed for the kitchens of 2025 households, planTree allows to grow organic food from seed to plants. Seeds or seedlings are placed into pot-like cups that are filled with soil substitute materials such as rockwool or coco fibre. Water and nutrients are added to system, where they are circulated through plants. A simple interface lets user to set up values such as pH, moisture and light. Plants are grown and cultivated in a controlled microenvironment with water, nutrients and humidity.PlanTree-Eco Technology3

Design allows cultivation of organic food at home with less water and more efficiently, saving time and energy. Designed by Nur Yıldırım, planTree was honored in International Design Awards 2011 with Silver Award in Kitchen Appliances Student Category.

Importance of healthy local food is increasing while there is a growing awareness on the agriculture methods. Organic farming is becoming popular due to concerns like genetically modified food plantation. Home farming is also spreading both for health concerns and as a hobby.

PlanTree is a vertical indoor plant grower composed of a base and modules. Organic food that is consumed at home can be grown on pot-like modules from seed to plant. With the user friendly interface and automated water recirculation, product is easy to keep and maintain.

PlanTree-Eco Technology2The base holds the water and the system components, while supporting the whole body. There are 8 holes for module columns on the base. Columns can go up to 6 modules in height, therefore 48 modules in number can be reached at maximum.

Modules are the parts holding plants and they can be combined in 3d space with various arrangements. Soil substitute materials are put into pot such as a sponge or as a mixture of small and big granules such as expanded clay and perlite. A cap is used to keep the water and heat for the seed while becoming a seedling. Then plant growth is sustained with a water and nutrient cycle.

Firstly, water and nutrients are fed to the system from the blue capped holes. Water is needed is 10 litres while maximum capacity is 20 litres. Nutrients are held in a different reservoir.

Water is pushed upwards from the base with the help of a pump. Water goes through channels that are numbered as columns. Water and nutrient solutions can be arranged according to columns if it is needed. Water is streamed downwards through modules, keeping the roots and supporting material wet. Green surface gives the necessary slope while also acting as a support material between transparent pieces.

PlanTree-Eco Technology4Interface of the product shows values for moisture, air temperature, water temperature and pH. Water level and nutrition level is shown while the light choice can be seen as sunlight or artificial light. There is a warning sign at the bottom to indicate that attention is needed.

pH level can be adjusted by changing the solutions concentration. Nutrient or water amount can be changed accordingly.

PlanTree-Eco Technology5Product is intended to be placed in kitchens or balconies connected to kitchen. Plenty of daylight can be absorbed when there is light. Otherwise flexible growleds provide necessary lights. Saving space by occupying only quarter of a metre square, plant number/space efficiency is achieved.

Illustration-PlanTree2The design solution brings a modular system that can be organized on a base which is carrying inner components while acting as a structural root for modules. System is fed by base in terms of water, light and nutrients. Modules offer the flexibility of space usage and quantity. System is expandable. It is also readily rearrangeable in 3d space with the help of turnable modules without the need of breaking them apart.

Illustration-PlanTree1Hydroponics technology is chosen for a number of reasons. Firstly, it is a more efficient way of cultivating when compared with soil culture in terms of water efficiency and yield health. Moreover, it is the latest technology in cultivating and used widely by industrial agriculture factories. Therefore, it is more suitable for a future project instead of conventional propagation techniques.

Illustration-PlanTree3Design uses organic modules each holding one plant. Modules are designed for space efficiency. User plants a seed into a module, than cap it. System is established by joining modules, water and nutrients are fed by base automatically. Lights are provided in case of low sunlight.

Eco Newspaper – A Concept

The invention of computers, e-readers, tablets, smartphones and other such devices has had brought down our use of paper to a considerably lower level. Imagine how much paper work would have been carried out if there would be no such devices. With the more advancements and utilization of the technology we will cut down the use of paper more in coming decades. There is a concept of Eco newspaper which can do that by replacing the traditional style of newspaper reading if it comes into reality in future.

As per the Eco newspaper concept, there will be a projector device that can project the daily news on the table counter-top. It’s not just about projecting text and imagines on table but you can flip pages on the projection as you would normally do in case of traditional newspapers. You can also select your newspaper as it will be connected to internet or to multiple cloud services of different news providers. The news then will be updated daily through these cloud services of news providers. It will also use a bio-battery power instead of normal battery to just make it more Eco-friendly. A variety of other digital functions can also be integrated into this Eco Newspaper. Perhaps the invention would also be able to read the reports to those who are visually impaired.
