Researchers from Asia and Europe have developed the world’s lightest and thinnest organic circuits, which in the future could be used in a range of healthcare applications.
Lighter than a feather, these ultrathin film-like organic transistor integrated circuits are being developed by a research group led by Professor Takao Someya and Associate Professor Tsuyoshi Sekitani of the University of Tokyo, who run an Exploratory Research for Advanced Technology (ERATO) program sponsored by the Japan Science and Technology Agency (JST), in collaboration with Siegfried Bauer’s group at the Johannes Kepler University (JKU) Linz, Austria.
The circuits are extremely lightweight, flexible, durable and thin, and conform to any surface. They are just 2 microns thick, just 1/5 that of kitchen wrap, and weighing only 3g/m^2, are 30 times lighter than office paper. They also feature a bend radius of 5 microns, meaning they can be scrunched up into a ball, without breaking. Due to these properties the researchers have dubbed them “imperceptible electronics”, which can be placed on any surface and even worn without restricting the users movement.
The integrated circuits are manufactured on rolls of one micron thick plastic film, making them easily scalable and cheap to produce. And if the circuit is placed on a rubber surface it becomes stretchable, able to withstand up to 233% tensile strain, while retaining full functionality.
“This is a very convenient way of making electronics stretchable because you can fabricate high performance devices in a flat state and then just transfer them over to a stretchable substrate and create something that is very compliant and stretchable just by a simple pick and place process.”
This prototype device is a touch sensor featuring a 12×12 array of sensors on a 4.8 cm x 4.8 cm circuit. It is made up of two layers, an integrated circuit layer and a tactile sensor layer.
With the development of these plastic electronics, the possibility for flexible, thin, large area electronics has been realized. In the future, the group would like to expand the capabilities of these circuits.
“The new flexible touch sensor is the world’s thinnest, lightest and people cannot feel the existence of this device. I believe this development will open up a wide range of new applications, from health monitoring systems, wearable medical instruments, and even robotic skins in the future.”
The results of this research were published in the July 25, 2013 issue of the journal Nature.

Yokohama National University professor emeritus Akira Miyawaki, who to date has planted over 40 million trees in 1,700 locations in Japan and overseas, is continuing his tree planting activities not only in Japan but also on twice monthly overseas trips.
“After 60-plus years of local research, currently in areas inhabited by 92.8% of Japan’s population of 128 million, the remaining evergreen forests consisting of deep and straight-rooted trees including shrine forests only make up 0.6% of Japanese land.”
Iwanumi City in Miyagi Prefecture suffered tremendous damage from the Great East Japan Earthquake. To prepare for the next disaster, Miyawaki is promoting natural selection through mixed and dense planting of multiple types of trees as he advocates the creation of forests that do not require oversight. Iwanuma City has incorporated Miyawaki’s philosophy in establishing the “1,000-year Kibonooka Project” in preparation for the next disaster.
“A big challenge was how to resurrect the areas affected by the disaster. Given this background, we launched the “1,000-year Kibonooka Project” as something that will last forevermore into the future. One of the goals is to limit the destructive force of tsunamis, as well as to use the forest as an emergency shelter and on a regular basis as a place where children can come to learn about protecting lives. We also want to make this a memorial park that will remember the tragedy for a thousand years into the future. We encountered various limitations, but we created this project also with the goal of achieving efficient use of debris.”
Tide protection forests to date have primarily consisted of a single type of tree such as red or black pine. But shallow-rooted pine trees were uprooted by the tsunami and did not serve their purpose.
Miyawaki proposed to efficiently use the tremendous amount of debris created by the disaster as a resource excluding toxic and non-decomposable material. Sorted debris is mixed with dirt and used to fill dug-out holes to create large mounds that are further covered with dirt.
In planting trees, primary constituent trees are selected that grow long, deep roots and match the potential natural vegetation of an area. Three to five saplings of various other vegetation that make up the forest in addition to the main constituent trees are planted per square meter. This will require weeding for the first two to three years, but no maintenance is required after that. Twenty years after the tree planting there will be an abundant forest that will remain generation after generation until the next ice age predicted to occur in 9,000 years.
The forest will function as a green barrier, and by making the mound high it will also protect against large tsunamis. By reducing the energy of a tsunami, the mound will reduce the height and speed of the tsunami, thereby increasing the potential to protect people and property.
“To date, based on decisions made by leaders of companies with foresight, we have created Miyawaki-type forests in Japan and abroad.”
“38 countries including those where we have conducted local surveys. We have planted trees on four continents.We talk about greening deserts, but two-thirds of the deserts on earth have been created by humans. The remaining 10% or so of absolute deserts will not support forests. These absolute deserts should remain as is. But areas that have been destroyed by humans can support forests.”
Pride One Entertainment’s Yasushi Akutagawa, who has expressed interest in Miyawaki’s simple efforts to protect the environment, is thinking of supporting the forest building movement through film.
“We want the people of the world to become aware of Dr. Miyawaki’s great work. We are thinking of using film as a way to make this possible. We want to assemble a group of leading Japanese actors, screenwriters, and film staff members to depict Dr. Miyawaki’s life. ”
“Humans have survived by turning crisis into opportunity. Thus we want to do what can be done now to survive the next natural disaster that will definitely come–which is to create forests that protect lives–and spread this know-how from Japan to the world. We want to turn crisis into opportunity by spreading forests of the 21st century from Japan to the world and have the world recognize their value.”

Stationary Observation System for High-speed Flying Objects
This camera system can track very fast moving objects, keeping them in the center of the screen at all times. Currently under development by the Ishikawa Oku Lab. at the University of Tokyo, this latest version captures Full HD video and can be used outdoors.
“Ordinarily, to change the direction a camera faces, you move the camera mechanically. But in this system, it’s not the camera that moves, it’s the mirrors. This makes it possible to change where you’re looking really quickly. In this demonstration, we’re tracking a table tennis ball. The ball moves extremely fast, but this system can keep compensating for the ball’s motion, so the ball stays in the middle of the image.”
This device consists of two mirrors for pan and tilt, and a group of lenses. The Saccade mirrors can be controlled at high speed, on the order of milliseconds. The mirrors move independently, so this system doesn’t lose its high-speed response even if it’s connected to a large, heavy camera.
Also, by connecting a projector instead of a recording device, images can be projected onto a fast-moving object. This could also be used in AR applications, showing interactive content on moving objects.
“Using a rotating mirror is a common method, but usually, the mirror is in front of the camera, so a very large mirror is needed. But a feature of this system is, it can even capture wide-angle images with a small mirror. That’s because the system contains special optics called a pupil shift system.”
“Another important point is, this system does very fast image processing to recognize the subject. It captures and processes an image every 1/1000th of a second. In this way, it can track the subject stably and continuously, simply by feeding back the subject’s position, without particularly predicting its behavior.”
“For example, this system can record, in great detail, the instant a player hits a home run, including how the bat bends and the ball reacts, and the ball’s subsequent path. Or in soccer, it can record things like penalty kicks in amazing detail. We think this will make it possible to shoot sports in a really compelling way.”
“Right now, we’re actually taking this outdoors to where sports are played, to check how accurately it works. We hope it will be usable for actual broadcasting in about two years.”

This multi-viewpoint robotic camera system, under development by NHK, links the motion of eight sub-cameras to that of an individual camera, so that all the cameras film the same moving object.
“Using this system, you can create the effect of stopping time, and moving the viewpoint all around the subject.”
“Previous methods used a fixed camera, so they could only capture subjects moving in a narrow or limited space. But this multi-viewpoint robot camera system can film dynamically moving sports, or subjects at lots of locations in an extensive space.”
Each robot camera has two motors, for pan and tilt. The cameras also share lens data, so they can zoom in unison.
“Pictures taken with robot cameras inevitably have discrepancies in direction control. So simply switching between them doesn’t give smooth pictures. To solve that problem, we’ve brought in a computer, which redoes the direction control virtually. Image processing is done, to virtually orient the cameras in the direction of the subject, making it possible to switch between the cameras.”
“Pictures from this system can be sent out about one minute after filming is finished. First of all, we intend to use this for live sports broadcasting. We’d like to make it easy to understand what’s happening, by providing multi-viewpoint pictures instead of the current slow-motion replay.”
This multi-viewpoint robotic camera system can also be used as an image capture system for integral 3D TV, under development by NHK. By generating integral 3D video from multiple-viewpoint footage, 3D video of sports events will be viewable on integral 3D TV.

This marketing analysis tool, under development by Fujitsu, uses technology to sense people’s movement. By analyzing how customers behave in response to merchandise, entirely new kinds of marketing information will be obtainable.
“This exhibit is designed with retail stores in mind. The system determines how people choose products, whether they were interested in a product already, and what products they compare, using Kinect and a camera.”
With regular POS systems, the only information obtained is how much merchandise has been sold. But by using this system, it’s possible to find out how customers acted while contemplating the purchase of a product. This system could help with marketing by showing how customers behaved when they were thinking about buying a product, but didn’t complete the purchase.
“For example, we think this system will make it possible to analyze how a person considered two products, found it hard to decide between them, and finally chose one of them. It’ll enable analysis to go deeper, regarding whether a person who had difficulty deciding was a man or woman, and how old they were.”
“Rather than using this system by itself, we think it could be used in conjunction with RFID tags and other sensors. Also, rather than using Kinect to detect people coming and going, it could be combined with more specialized sensors. In fact, all this system does is collect data, so when it comes to analysis, it could be cross referenced with point of sale data and big data, or the system could be used to correlate information regarding the effectiveness of introducing customer loyalty points programs. So, we hope this system will be utilized in combination with Fujitsu’s all-round solutions.”
