Polymer International, EarlyView.An overview and categorization of man‐made per‐ or polyfluoroalkyl substances (PFASs) including low‐molar‐mass and high‐molar‐mass fluorochemicals, and their international regulations is presented. Though certain PFASs are toxic, bioaccumulative and cross the human cellular membranes, others, such as fluoropolymers, are safe, reliable and involved in ...

An Ergonomic Customizable Soft Robotic Glove Toward Personalized Hand Rehabilitation
SmartBot, EarlyView.Soft robotic gloves for hand rehabilitation are often limited by poor fit and uneven pressure on the fingers. Here, the authors report an ergonomic all‐fabric glove whose dual‐action actuators are tailored to individual finger geometry by CNC heat sealing, with symmetrical chambers that distribute interface pressure more evenly. Weighing only 90 g, the
