From now on it will be possible to accurately monitor and analyse how stroke patients move during everyday life. This involves the use of a new suit fitted with 41 sensors, plus the infrastructure needed to transmit, store and process all of the data collected. This technology and information will make it possible to improve the rehabilitation process and cut healthcare costs. Bart Klaassen developed the system together with an international team of engineers and healthcare professionals. He will defend his thesis (which is based on this research) on 30 November, at the University of Twente. “The technology is finally ready.”

As many as 33 million people throughout the world suffered strokes in 2010...

Researchers at NTU Singapore have 3D printed a ready-to-fly drone with embedded electronics. The electronics were incorporated in the drone during the 3D printing process which employs Stratasys ULTEMTM 9085 – a high strength, lightweight FDM material used in commercial aircrafts. The drone is jointly developed by NTU’s Singapore Centre for 3D Printing (SC3DP) and Stratasys Asia Pacific, a 3D printing and additive manufacturing company. The drone -quadcopter with 4 rotors – was designed, 3D printed and flown by Phillip Keane, PhD candidate.

Embedding electronics can be a challenge, as most will not survive the high temperatures of the 3D prin...

Technion researchers have demonstrated, for the first time, that laser emissions can be created through the interaction of light and water waves. This “water-wave laser” could someday be used in tiny sensors that combine light waves, sound and water waves, or as a feature on microfluidic “lab-on-a-chip” devices used to study cell biology and to test new drug therapies. For now, the water-wave laser offers a “playground” for scientists studying the interaction of light and fluid at a scale smaller than the width of a human hair.

The study is the first bridge between two areas of research that were previously considered unrelated to one another: nonlinear optics and water waves...

As well as being the thinnest, strongest and lightest known material, graphene is flexible, impermeable and extremely electrically and thermally conductive. All properties well suited for next generation NFC antennas. Credit: Image courtesy of Graphene Flagship

Near-field communication (NFC) is a set of communication protocols that enables 2 electronic devices to transfer data. The most distinctive characteristic of NFC is the fact that it can transmit small amounts of data wireless only within a close range while other methods, such as Bluetooth and Wi-Fi, have a wide transmit range of up to 10 or even 100m. The reason why NFC technology is used to identify objects is that, with such a close transmitting range, it is more secure and less vulnerable to data hijacking...
