Infrared 3D scanners have been used in video games for quite some time. Whereas in video games the scanners are, for example, only able to identify if a player throws his arms up in the air while playing virtual volleyball, the new 3D scanner of Fraunhofer Institute for Applied Optics and Precision Engineering is able to be much more precise. With a resolution of 1 million pixels and real-time data processing, numerous applications are possible with this new device.

“The measuring technology works in a similar way to human vision. However, instead of 2 eyes we are using 2 near-infrared cameras,” Stefan Heist from Fraunhofer IOF explains...

The “Smart Scar-Care” pad designed by Professor Cecilia Li-Tsang in the Department of Rehabilitation Sciences, PolyU, serves the dual functions of reinforcing pressure and occlusion.

An innovative pad with dual functions of reinforcing pressure and occlusion has been designed by researchers to treat hypertrophic scars from burns, surgeries and trauma. It showed good performance in reducing pigmentation and vascularity, improving elasticity and preventing dehydration in a clinical trial. It is more durable and user-friendly compared with the traditional pad (polyethylene foam) as reported by the patients...

Photographs of hydrogel dressing in the original form (a) and with the addition of chitosan (132 kg mol−1, 0.5% (w/v)) dissolved in LA (b).

A new dressing, a type of compression held in place by a bandage, uses an antibacterial substance formed from the shells of crustaceans like shrimps. Antimicrobial resistance is becoming a worldwide health threat. A recent report by the Review on Antimicrobial Resistance warns that antimicrobial resistance could kill 10 million people each year by 2050, dwarfing even the number of estimated deaths from cancer. Because of this, preventing infection has never been more important.

The protective dressing was developed by Dr. Radoslaw Wach and his colleagues from Lodz University of Technology in Poland...

Takuro Iwata, Takashi Katagiri, Yuji Matsuura. Real-Time Analysis of Isoprene in Breath by Using Ultraviolet-Absorption Spectroscopy with a Hollow Optical Fiber Gas Cell. Sensors, 2016; 16 (12): 2058 DOI: 10.3390/s16122058

Affordable gas sensor setup developed by Tohoku University team monitors trace levels of health-indicating chemicals, paving the way for future non-invasive studies. Using hollow-core optical fibre as a sensitive gas cell, researchers in Japan have devised a relatively simple and affordable sensor for monitoring biomarkers in human breath at low concentrations. Trace amounts of gases exhaled through the nose and mouth offer clues to respiratory conditions such as asthma, as well as other easy-to-administer health screening opportunities.
