Stretchable, degradable semiconductors for health monitoring

Zhenan Bao has developed stretchable, degradable semiconductors, with the ability to conform to internal organ surfaces, and dissolve and disappear when no longer needed. This is the first example of a material that simultaneously possesses the three qualities of semiconductivity, intrinsic stretchability and full degradability. Other attempts resulted in semiconductors that either did not break down […]

Sweat sensor monitors metabolites to detect gout, metabolic and other disorders

Caltech’s Wei Gao has developed a wearable sensor that monitors metabolites and nutrients in blood by analyzing sweat. Previously developed, less sensitive, sweat sensors mostly target electrolytes, glucose, and lactate. Gao develops devices based on microfluidics, which minimize the influence of sweat evaporation and skin contamination on sensing accuracy.  Previous microfluidic-based wearable sensors were mostly fabricated with a […]

Wireless, wearable sticker adds a sense of touch to VR

John Rogers, Yonggang Huang and Northwestern colleagues have developed an “epidermal VR” system that adds a sense of touch to any virtual reality experience. The device incorporates a distributed array of 32 individually programmable, millimeter-scale actuators, each of which generates a discrete sense of touch at a corresponding location on the skin. Each resonates most strongly […]

Silk patch measures 6 biomarkers in sweat

Wenya He, Yingying Zhang, and Tsinghua and Northwest School colleagues  have developed a silk-based wearable patch which measures glucose, ascorbic acid, lactate, potassium, sodium ions and uric acid concentrations in sweat. Sensors are embedded in a woven graphite-silk fabric. Conductivity is enhanced using graphite doped with nitrogen atoms. The flexible patch is applied to the […]

3D printed skin, with blood vessels

Pankaj Karande and Rensselaer Polytechnic Institute colleagues have developed 3D printed living skin, with blood vessels. which could integrate with host cells in grafts. Until now, a significant barrier to integration has been the absence of a functioning vascular system. Karande previously made two types of living human cells into “bio-inks,” and print them into a skin-like […]

High resolution brain map traces wiring within, between, thalamus and cortex

Allen Institute scientists have created a high-resolution brain map, which traces thousands of connections between brain areas in mice, which they believe  can help us understand how brain circuitry changes in diseases and disorders such as Alzheimer’s disease and schizophrenia. This is the most detailed map of connections in a mammalian brain to date, tracing neural […]

November 14 – Harvard Medical School

Join ApplySci at the 12th Wearable Tech + Digital Health + Neurotech Boston conference on November 14, 2019 at Harvard Medical School featuring talks by Brad Ringeisen, DARPA – Joe Wang, UCSD – Carlos Pena, FDA  – George Church, Harvard – Diane Chan, MIT – Giovanni Traverso, Harvard | Brigham & Womens – Anupam Goel, UnitedHealthcare  – Nathan Intrator, […]

Pacifier sensor detects glucose levels in babies

UCSD’s Joe Wang has developed a soft, flexible, pacifier-based biosensor that continuously monitors glucose levels in saliva to detect diabetes in babies. Until now,  continuous glucose monitoring in newborns,  available only in major hospitals, requires piercing the infant’s skin to reach interstitial fluid. The team created a proof of concept pacifier where small amounts of saliva […]
