Organic electrochemical transistors

Artificial neuron transmits chemical signals

An artificial neuron architecture based on antiambipolar organic electrochemical transistors shows responses to biological ions and neurotransmitters akin to real neurons with comparable speed. The soft and more biocompatible nature of organic semiconductors could enable applications in brain–machine interfaces and in vivo sensing.
