A substrate-less nanomesh receptor with meta-learning for rapid hand task recognition

Prof. Zhenan Bao et al present a novel, electrically active, spray-on smart skin that uses AI to rapidly decipher typing, sign language, and the shape of a familiar object from the movements of a human hand even with limited training.

Wireless closed-loop smart bandage for chronic wound management and accelerated tissue regeneration

Prof. Zhenan Bao, Prof. Geoffrey Gurtner et al have developed a prototype wireless smart bandage that speeds tissue repair, promotes faster closure of wounds, increases new blood flow to injured tissue, and enhances the recovery of skin.

Insights into the mechanical properties of ultrathin perfluoropolyether−silane coatings

Prof. Reinhold Dauskardt et al determined that for film used as an anti-fingerprint coating on touchscreen displays, humidity and other field operating conditions affect film properties making optimal cross-linking characteristics less certain, as well as the precursor chemistry to achieve them.
