Harvesting energy from insects in quest to create tiny cyborg first responders

An insect fitted with piezoelectric generator to harness the energy from the insect's wing.
Insects have served as the inspiration for a number of Micro Air Vehicles (MAVs) that could be deployed to monitor hazardous situations without putting humans in harm's way. Now researchers at the University of Michigan College of Engineering are proposing using actual live insects enhanced with electronic sensors to achieve the same result. The insect cyborgs would use biological energy harvested from their body heat or movements to potentially power small sensors implanted on their bodies in order to gather vital information from hazardous environments.

To harvest energy from insects, the researchers have designed a spiral piezoelectric generator that converts the kinetic energy from the insect's wing movements into electricity. This power would be used to prolong the battery life of devices implanted on the insect, such as a small camera, a microphone or a gas sensor. The prototype piezoelectric generator was fabricated from bulk piezoelectric substrates and was designed to maximize the power output in a limited area.

"Through energy scavenging, we could potentially power cameras, microphones and other sensors and communications equipment that an insect could carry aboard a tiny backpack," said Professor Khalil Najafi, the chair of electrical and computer engineering at the U-M College of Engineering. "We could then send these 'bugged' bugs into dangerous or enclosed environments where we would not want humans to go."

The U-M team examined several techniques to scavenge energy from wing motion with their results were published in a paper titled "Energy scavenging from insect flight," which was recently published in the Journal of Micromechanics and Microengineering. The university is now pursuing a patent for the technology and is seeking commercialization partners to bring it to market.

Getting the insects to go where their handlers want them to is another part of the puzzle that needs to be solved before insect cyborgs can be deployed. But DARPA has been working on this, having put out a call some years back for research proposals for Hybrid-Insects-Micro-Electro-Mechanical System (HI-MEMS) interfaces to control the movement of living insects. Combining the two technologies could be just the thing to take insect cyborgs to the next level and see them used to monitor hazardous situations in the not to distant future.

Shredder Clock




There is a new clock that makes you wanna wake even if you don't want to cause you can't afford not to.
The Shredder Clock is just a concept, but it’s a pretty good idea, and a new spin on the notion that money is a great morning motivator. Other alarm clock inventions force you to feed them money before they’ll shut up, or automatically donate to charities that you hate until you get out of bed, but this one lets you see your money going to waste.
You could conceivably shred anything you find precious, from letters to pictures, not just money even summons if you want to risk going to jail.
This actually seems like a decent DIY project — it probably wouldn’t take much work to sync a paper shredder to your alarm clock although the outcome won't be as good as this.


Janken with 100% Winning Rate Robot

The game Janken or rock-paper-scissors is so famous that almost everyone know how to play it. In fact, recent news in the world of technology reveals the ability of a robot hand to play this game, and you'll never beat it.
The robot hand on the right is designed to have 100% winning rate
This robot was developed by Ishikawa Oku Laboratory (Japan, obviously) and with the super-duper high-speed sensor that'll read opponent's hand gesture, the robot will make a counter move that will beat the human's move.

Here's the video.
The purpose of this highly frustrating machine (cause you play the game and lose everytime) is to demonstrate its ability in real world situation where the robot must be able to react like human when necessary.

I hope the researchers can tweak the algorithms so that it can play rock-paper-scissors-lizard-spock just like in the series The Big Bang Theory.
Here's the graphical representation as to what Sheldon Cooper said in the video.

Certainly technology has advance quite fast and hopefully all of these achievements can give benefit to human in a peaceful way. 

50 Gigapixel Camera

A group of engineers from Duke University and University of Arizona recently have managed to build a camera with 5 times better than human vision of 20/20.

The camera was built by synchronizing 98 tiny cameras into one device and a computer processor will then compiles all the image captured by the cameras using a software developed by a team led by Michael Gehm.

The 50 Gigapixel Camera with 2 and half feet square and 20 inches deep

The typical consumer camera ranges from 8 to 40 megapixels only and by comparison, the image produced by this new camera will have 12++ more pixels than consumer camera. This undoubtedly will create an image with excruciating details.

Even with the 50 Gigapixel of resolution, the optic part of the camera only constitutes around 3% of the overall size of the camera and the rest is divided into processors and electronics used to assemble the information gathered by the optic.
Example of a picture taken by the high resolution camera
Currently, the highest amount of pixels in a picture is 272 Gigapixels, created by Alfred Zhao using 12000 images all taken in Shanghai, China. You can see the picture and the amount of details in this website. Engineers in this team claim that with smaller electronics and processors are being made, camera with this resolution may be able for general consumer and everyday photographers.

No 'Blind Spot' Side Mirror

Dr R. Andrew Hicks, a math professor at Drexel University has successfully eliminates 'blind spot' in current design of side mirror by introducing a curved side mirror. Normal side mirror is often flat, giving you around 17 degrees field of view. This revolutionize side mirror, on the other hand, can give you field of view around 45 degrees, allowing you to see more as compared to flat side mirror.

The curvy side mirror might gave you a wider field of view but the visual distortion on the mirror which can make straight line looks curvy presents with great risks, hence no car companies want to try and use it. But Dr Hicks invention on the other hand is created with mathematical algorithm so that the visual distortion is minimized and in his invention, the curvy straight line is barely detectable, suggesting low visual distortion, but still, object appears in a distance when in reality it is much closer.

In the curvy mirror above, the silver car is seen at a distance but is much closer in reality. However,
the field of view in above mirror allows driver to see details that aren't present in flat mirror.
The metaphor given by Dr Hicks to his invention is like disco balls bouncing off light. We can imagine the mirror's surface is created with thousands of smaller mirrors and the algorithm will manipulate each of these smaller mirrors' direction so that the resulting big mirror will give wider view to the driver without distorting the visual appearance on the mirror.

His invention though great, but it won't be installed in any new car soon because of US regulations that a car must have flat side mirror or a phrase 'Objects in mirror are closer than they appear' must be included for curve mirror. Nevertheless, this is a good invention to eliminate the high statistics of vehicle accidents in the whole wide world. Dr Andrew Hicks also have designed several bizarre mirrors.

Eidetic Memory

Eidetic comes from Greed word eidos which means "seen". Eidetic memory means the ability to recall any visual/audio events with perfect accuracy and details. People who claim to have this kind of memory possess the skills to exactly remember an event, for example the event in a ball room, where he/she can recall where the person was standing, the people around him/her, the shirt they were wearing, food they ate down to what kind of conversation that they were having.

There are several series depicting a genius with this kind of memory for example Dr Spencer Reid in Criminal Minds and Dr Sheldon Cooper in The Big Bang Theory. In real life however, the case of eidetic memory have yet to be understood fully but there are a few who claim to have this memory for example Stephen Wiltshire, a British architectural artist that can draw a landscape after seeing it once. Another person, Daniel Tammet, also a British citizen, who can recall the number pi up to 22 000 digits.

Dr Spencer Reid holds Ph.D in Math, Chemistry and Engineering
as well as B.A. in Philosophy.
Dr Sheldon Cooper portrayed by Jim Parsons in The Big
Bang Theory.
Psychologically, people who have eidetic memory sometimes suffer from a condition known as autism, a medical condition characterized by problems in social interaction and communication together with repetitive behavior. Generally, people who have eidetic memory suffer also with autism but people who suffer from autism may not have eidetic memory.

The video is a documentary about Daniel Tammet

There are several myths involving photographic memory especially as to whether normal people can acquire it or not. Most of the techniques that claim to help you acquire this memory are actually memory improvement technique, not the actual eidetic memory. Nevertheless, it is always good to improve your memory as it may helps you from time to time.
