Sensor assesses blood clotting in 30 minutes
ClotChip assesses blood clotting 95 times faster than current methods, with a single single drop of blood, using miniaturized dielectric spectroscopy. A finger-prick sample is taken from heart arrhythmia, pulmonary embolism, post surgery, or hemophilia patients, to analyze clotting abilities in the ER or at home. Results are received in 30 minutes. Caregivers currently cannot quickly assess if…

Eye implant measures pressure, releases fluid, in glaucoma
Caltech’s Azita Emami, Aubrey Shapero, Abhinav Agarwal and colleagues have developed a miniaturized, fully wireless, highly-sensitive, implantable, continuous pressure sensor that can remain in the human eye for four years. The goal is early detection and treatment of glaucoma progression. Current tonometer measurement, which requires anesthesia, only measures pressure during an appointment, and can miss…

Cheap, molecular-wired, metabolite-measuring sensor
Cambridge’s Anna-Maria Pappa, KAUST’s Sahika Inal, and colleagues have developed a low cost, molecular wired sensor that can measure metabolites in sweat, tears, saliva or blood. It can be incorporated into flexible and stretchable substrates for cellular-level health monitoring. A synthesised polymer acts as a molecular wire, accepting electrons produced during electrochemical reactions. It merges…

“Artificial nerve” system for sensory prosthetics, robots
Stanford’s Zhenan Bao has developed an artificial sensory nerve system that can activate the twitch reflex in a cockroach and identify letters in the Braille alphabet. Bao describes it as “a step toward making skin-like sensory neural networks for all sorts of applications” which would include artificial skin that creates a sense of touch in prosthetics. The artificial…

Body heat-powered, self-repairing health sensor system
Hossam Haick at Technion-Israel Institute of Technology has developed a body heat powered, self-repairing system of sensors for disease detection and monitoring. Unlike other wearables, the ability to derive energy from the wearer, and to fix tears and scratches, prevents the need to turn off the device for repair or charging, allowing truly continuous tracking.…

Ingestible “bacteria on a chip” detects blood, inflammation
MIT’s Timothy Lu has developed an ingestible sensor with embedded genetically engineered bacteria to diagnose bleeding or other gastrointestinal issues. The “bacteria-on-a-chip” approach combines living cell sensors with ultra-low-power electronics that convert the bacterial response into a signal read by a phone. The technology has only been tested in pigs, but shows promise in detecting…

Cheap, noninvasive patch monitors glucose
UCSD’s Joe Wang‘s needless adhesive glucose monitor has begun a phase I clinical trial. The small patch measures insulin levels through sweat on the skin, eliminating the need for a skin prick. The paper – tattoo is printed with two integrated electrodes that apply a small amount of electrical current. Glucose molecules residing below the skin are…

BP cuff + accelerometer detect early preeclampsia
Purdue’s Craig Goergen has developed a sensor-based supine pressor test to detect preeclampsia. The technology measures and notes the difference between a pregnant woman’s diastolic blood pressure while in two different positions, using a BP wrist cuff and accelerometer on the stomach. The two devices are connected to an app which guides the wearer, and…

Gait sensor could detect Alzheimer’s, identify fall risk
Newcastle University’s Lynn Rochester has studied the use of wearable sensors to identify walking characteristics as clinical biomarkers for Alzheimer’s Disease. The same sensors can detect gait changes that require intervention to prevent falls and prolong independence. According to Rochester, “free-living gait analysis at home is particularly useful as it allows objective observation of an…

Saliva-monitoring chip to track bone loss, diabetes, inflammatory markers
Washington University’s Erica Lynn Scheller and Shantanu Chakrabartty are developing a gum or dental device-worn sensor to detect early signs of disease by analyzing saliva or gingival crevicular fluid. The sensor plus electronic chip is a few millimeters-cube in volume and measures disease-specific peptides. A wireless ultrasound device reads the peptide levels and connects to the cloud.…
