Artificial nociceptor based on temperature responsive of synaptic transistor for electronic skin

Abstract

• A temperature-sensitive artificial nociceptor was developed. • The nociceptor incorporates thermoreceptors and intrinsically neuromorphic transistors. • This device combines sensory and memory functionalities. • The modulation of synaptic plasticity through electrical methods and variations in temperature. Health monitoring can be facilitated by electronic skin devices that possess the ability to detect signals. The capability of human skin to sense and remember temperature plays a crucial role in perceiving and monitoring physiological changes within the human body. The anticipated capabilities of electronic skin closely resemble those of human skin. We have successfully developed a temperature-sensitive artificial nociceptor that incorporates thermoreceptors and intrinsically neuromorphic transistors. This device combines sensory and memory functionalities by utilizing synaptic transistors, which allow for the modulation of synaptic plasticity through electrical methods as well as variations in temperature. The proposed features include temperature-responsive operations, spontaneous recuperation, and multi-trial learning that is influenced by temperature. The temperature-sensitive neuromorphic capabilities of the synaptic transistor, coupled with its self-repairing properties, resemble those found in human skin for sensing, storing information, and recovering from external stimuli. This work is anticipated to greatly contribute to the advancement of wearable electronics, intelligent robotics, and prosthetic applications.
