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 […]
