Another wearable tattoo that shows your vital body functions

e-skin wearable tattoo

Wearable technology is going to influence our daily chores in a big way, if already it hasn’t started doing so. One application of this is the use of electronic tattoos that is still in the infancy stage, but none the less impactful. Going by this notion, a team headed by Takao Someya at the University of Tokyo have developed a prototype e-skin which is the thinnest so far at just 3 micrometers. The artificial skin embraces any part of your body and lies on your skin like a food wrap. It has a LED display which displays user’s vital stats like heart rate and blood oxygen levels.

Electric fork stimulates salty flavor in salt-free meals, boon for hypertensive patients

Electric fork for salty flavor

Researchers of the Hiromi Nakamura at Rekimoto Lab, Interfaculty Initiative in Information Studies, University of Tokyo, have good news for blood pressure/hypertensive patients who are on low-salt or salt-free diet. Researchers have developed an ‘electric flavoring fork’ based on the ‘electric flavoring technology’ under development at the university. Read More…

Rock-paper-scissors robot enjoys 100 percent success rate against humans


Researchers are not only working on robots that help make life easy for us. They are already building robots to compete with the humans and also amid themselves – ready for a robot war are you? Realistically, we have seen a ping pong robot nearly impossible to defeat; and here we have a rock-paper-scissors robot delivered onto us by researchers in Japan. The robot is not just good at the Janken (aka rock-paper-scissors), perhaps it’s the best humans have come to know. Read More…

Self powered wearable armband sounds alarm in case of fever

self-powered fever alarm armband

Researchers at University of Tokyo have developed a smart wearable device that sounds an alarm when the wearer runs a fever. Named Fever Alarm, the self-powered armband comes with a silicone solar panel and a thermal sensor to detect body temperature of the wearer ranging between 36.5C and 38.5C. Thus, the wearable can sound the alarm when wearer’s body temperature either falls one degree than the average of 37C or rises high than it. Besides incorporating a silicone solar panel, the fever alarm armband is packed with a piezoelectric speaker, temperature sensor and an organic power supply circuit.

Sticky sensors that attach to body tissue for biometric readings to the core

Sticky sensors for biometric readings

Researchers in Japan at the University of Tokyo have invented a sticky sheet of small little sensors that can be attached directly to moving joints, beating hearts or living tissue. This new innovation will open-up new avenues in medical science with the ability to implant these sensors inside the body to keep a tab on the physical changes that occur. For example when these sensors are attached to the heart, they can detect a blockage or anomaly in the blood flow from the arteries.

Sensory diaper signals caretaker on first sign of poop or pee

Sensory diaper

Determining whether your baby’s diaper is wet or not could become hassle free task as research team at The University of Tokyo have developed the world’s first flexible wireless (RFID tag) organic sensor system, capable of alerting the care taker about even a small trace of wetness in the diaper. This advanced diaper is fitted with disposable sensors that monitors wetness, pressure and temperature inside the diaper. The team headed by professors Takayasu Sakurai and Takao Someya have created flexible integrated circuit, embedded on to plastic film that transmits information and receives its power wirelessly. This saves the care taker from opening and closing the diaper after visual or smell clues. You just have to come close to the indicator fitted in the diaper, and if it indicates wetness or humidity, you can change the diaper instantly.

MUWA robot design can self propel in land, air and water

MUWA robot design

Imagine a lightweight bicycle wheel that can self propel itself in land, air and water. Well, that in a nutshell describes the one and only MUWA (or Multi-field Universal Wheel for Air-land Vehicle), an all-terrain foam-encircled quadrotor. Designed by a group of students at the University of Tokyo, the foam based robot is capable of balancing itself along its rim surface, thus functioning as a moving wheel on land. However, when it comes to air and water, the entire form can turn sideways (like a flying saucer) to makes use of the larger surface area for flying as well as floating.

Virtual projection keyboard technology with haptic feedback on palm of your hand

Virtual projection keyboard technology with haptic feedback on palm of your hand

3D projection systems and interfaces are going to be the future of technology implied in gizmos and gadgets which already are an integral part of our life. Just like the 3dim Tech’s gesture control technology, the design team over at University of Tokyo headed by professor Masatoshi Ishikawa and Hiroyuki Shinoda have developed a interface system that projects a virtual keyboard or any other interactive display on your hand, paper or any other random surface for providing input to your gadget(s). Powered by around 2,000 ultrasonic wave emitters that provide haptic feedback for action or pressure on the keyboard keys that are virtually projected on your hand, the new technology has immense potential for the future.

Book Flipping Scanning system turns any physical book into eBook within few minutes

Assistant Professor Masatoshi Ishikawa, Yoshihiro Watanabe, Takashi Komuro, Takashi Nakashima and H. Shibayama from the University of Tokyo have devised an ingenious new system to digitize books by just flipping them in front of a high speed camera. Masatoshi calls it Book Flipping Scanning (BFS) as it can scan at the speeds of 250-300 pages per minute and then the captured images are processed and stored in digital format. Ishikawa and his colleagues have created this technology to digitize books especially the ones biting dust in libraries so that the younger blood take more interest in reading such stuff. Once the book is captured using the Turner it is then observed in a monocular sequence and the reconstruction of 3D surface is done to form a flat format document that is appealing to the reader.
