Current opinions on the present and future use of functional near-infrared spectroscopy (fNIRS) in psychiatry

Prof. Allan Reiss, Prof. Manish Saggar, Prof. Hadi Hosseini et al discuss many applications of fNIRS in psychiatry, protype wearable fNIRS devices, and future integration of EEG, eye tracking, heart rate and artificial intelligence to enable effective personalized monitoring, diagnosis, and treatment for patients with psychiatric disorders.

Neuromorphic sensorimotor loop embodied by monolithically integrated, low-voltage, soft e-skin

Prof. Zhenan Bao et al report an electronic skin that incorporates organic semiconductor transistors and has no rigid components, thus mimicking aspects of real skin in mechanical properties, sensing temperature and pressure and can encode these stimuli into electrical pulses.

Multi-omics microsampling for the profiling of lifestyle-associated changes in health

Prof. Michael Snyder et al describe a strategy for the frequent collection and analysis of thousands of metabolites, lipids, cytokines and proteins in 10 μl of blood alongside physiological information from wearable sensors and demonstrate its advantages for discovering individualized inflammatory and metabolic responses to complex dietary changes and for deep individualized profiling.

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.
