Adaptively Responsive Self-Powered Bionic Auditory Device for Sleep Health Monitoring
IEEE ELECTRON DEVICE LETTERS(2023)
摘要
Drawing inspiration from adaptively responsive capability of biological auditory, we have developed a self-powered bionic auditory device that mimics the behavior of intelligent biological information recognition. The device comprises a triboelectric nanogenerator (TENG), a synaptic transistor, and an effector. The TENG has a wide range of sound pressure and frequency recognition capabilities, allowing it to convert dynamic sound pressure into the gate voltage of the synaptic transistor. The effector is triggered when the excitatory post-synaptic current reaches a threshold. The unique bionic synaptic device enables it to respond adaptively to sound signals in real-time. This innovative design enables the bionic auditory device to detect and process sound information in an adaptive and responsive manner.
