Eurekalert April 2, 2018 Researchers at Texas A&M used thickening agent known as kappa-carrageenan, obtained from seaweed, to design injectable hydrogels simulating the structure of human tissues. When kappa-carrageenan is mixed with clay-based nanoparticles, injectable gelatin is obtained. The charged characteristics of clay-based nanoparticles provide hemostatic ability to the hydrogels. Specifically, plasma protein and platelets form blood adsorption on the gel surface and trigger a blood clotting cascade. These bandages can show a prolonged release of therapeutics that can be used to heal the wound…read more. TECHNICAL ARTICLE

Palmreaders? Japan team builds second skin message display
Physorg February 18, 2018 Researchers in Japan have invented a band-aid-like stretchable device which is one millimetre thick and can monitor important health data as well as send and receive messages, including emojis. The display consists of a 16-by-24 array of micro LEDs and stretchable wiring mounted on a rubber sheet and a lightweight sensor composed of a breathable “nanomesh” electrode, and a wireless communication module. It can be placed on the human body for a week without causing skin inflammation. It has medical applications and wearable displays… read more.
