Glucose monitoring breath test
Applied Nanodetectors is in the early stages of developing a noninvasive breath sensor for diabetics to monitor daily glucose levels. By measuring the levels of volatile organic compounds in breath, if accurate, this could replace finger pricking for disease sufferers, and create a simple diagnostic test. The company has a related product that monitors the concentration of exhaled…

“Bubble-pen” writes with nanoparticles
Yuebing Zheng and University of Texas colleagues have developed a “bubble pen lithography” device and technique to quickly, gently and precisely handle nanoparticles. This can support the creation of accurate and highly sensitive biomedical sensors for drug delivery or imaging, among other applications. The method relies on micro bubbles to inscribe nanoparticles onto a surface. A laser is…

Sensor patch, app, quantify sun exposure
MC10 has partnered with L’Oreal to develop MyUV Patch, a small, flexible adhesive patch that uses MC10’s advanced sensors to determine sun exposure. Photosensitive dyes incorporate skin tone into the equation, and change colors as UV exposure increases. Users upload photos of the changing patch to an app that determines exposure levels. Last year ApplySci described…

Smart thermometer + app track temperature over time
Thermo by Withings is a connected, highly accurate, non invasive thermometer. It measures temperature from the temporal artery on the side of the head using 16 infrared sensors. 4,000 measurements are taken in 2 seconds, and a proprietary algorithm corrects for differences including skin heat loss or heat from a room’s light. Data is sent…

“X ray” vision for fall prevention, motion detection
Dina Katabi and MIT colleagues are using radio signal based software to recognize human silhouettes through walls, and track movements. The technology is intended to help monitor children and the elderly, and could be used by the military and the police. The signal is displayed on a screen, where movements are tracked in real time. The person is…

Robotic “glove” helps sight-impaired navigate, sense, grab objects
University of Nevada’s Yantao Shen is developing a hand-worn robotic device to help blind and sight impaired people navigate around obstacles, or locate, sense and grasp objects. Examples include picking up a glass or operating a door handle. The technology combines vision, tactile, force, temperature and audio sensors. According to Shen: “The visual sensors, very high…

Mobile 3D imaging for early breast cancer detection
Vayyar is a 3D imaging company that aims to turn every mobile device into an advanced imaging system. The company, which focuses on breast cancer detection, among other applications, claims that it can better detect anomalies, at an earlier stage, than traditional methods. The technology will be demonstrated at CES next month. ApplySci looks…

Flexible hydrogel bandage senses temperature, releases medicine
MIT’s Xuanhe Zhao has designed a bandage that releases medicine in response to changes in skin temperature. It can be programmed to light if wound attention is required, such as when medicine is low. The flexible, gel-like material incorporates temperature sensors, LED lights, other electronics, and tiny, drug-delivering reservoirs and channels. Zhao believes that hydrogel coated…

Wearable, home, school sensors + app predict asthma attacks
ApplySci is pleased to report another sensor-based initiative to combat asthma. Alex Bui and colleagues from UCLA and USC are creating technology for smart phones and watches to identify asthma attack triggers. The program is part of the National Institute of Biomedical Imaging & Bioengineering’s Pediatric Research using Integrated Sensor Monitoring Systems initiative. The platform will transmit data to a phone from…
