Antibacterial, Antifreezing, and Tough Electronic Skin Based on a Tanned Collagen Fiber Network for Underwater Grabber Application

The environment of underwater salvage is very special, and many factors such as real-time water conditions, the depth of salvage, and the complexity of underwater conditions could greatly affect the smooth progress of the salvage process. How to accurately judge the type of underwater salvaging item is an important topic in improving the efficiency of underwater operations. Herein, following the "top-down" strategy, a leather-based conductive electronic skin (e-skin) PLZAG was designed and constructed by using the collagen fiber network of zirconium-tanned leather. The resulting PLZAG e-skin exhibited high toughness, high modulus, and high sensitivity. It showed 65% of the maximum fracture strain and 12.28 MPa…
