Fabrication of self-powered 2D MoS2 field-effect synaptic transistors actuated by triboelectric nanogenerators for neuromorphic application

The development of neuromorphic devices and sensory networks has led to the creation of new systems similar to human brains. Anartificial synapse can be used to perform various functions, such as long-term potentiation, depression, and spike-timing-dependentplasticity. Various types of synaptic electronics can be used to develop sensory neurons. Some of these include three-terminal devicesand memristors with neuromorphic configurations. However, a particular device ideal for neuromorphic applications is a field-effecttransistors based on the two-dimensional layered semiconductor. To reduce the energy consumption of artificial sensory neurons, aself-powered neuromorphic system can be developed that can operate on mechanical energy. This strategy can be useful indeveloping systems that are energy-efficient.This project aims to develop a functional and biological self-powered artificial synapse sensory system similar to the humansomatosensory system. This will allow engineers to create self-powered electronic sensors, actuators, and communicators capable ofhandling biological intelligence. This project (FAST_TRIBONIC) involves the development of high-performance field-effect synaptictransistors with 2D MoS2 layered semiconductors and the construction of powerful triboelectric nanogenerators (TENGs) for the effectiveconversion of mechanical energy into electricity. Also, to develop an indigenous neuroelectric interface (artificial electronic skin) by integrating synaptictransistors and TENG during non-academic placement. By coupling TENG and field-effect transistors, a new fieldof tribotronics has been established for devices such as memory chips and tactile sensors. These technologies are expected to play avital role in developing modern high-performance, energy-efficient self-powered wearable electronic devices.
