Bio-inspired sensor systems based on ion transport, not electronics

Nanowerk.com - 16 июня, 2020 - 11:31
Many biological systems transmit signals via ions or molecules, whereas man-made sensors are mainly based on electron transport systems, i.e. electronics. The concept of ionic sensory systems is inspired by ion transport in biological systems, which is the movement of ions across a membrane, passively through ion channels or actively through ion pumps. Although sensory systems based on accurate ion transport are still in their early development, recent progress in nano-ionic sensory systems underlines their significant potential.
