Development of the next generation of bio- and nano-electronics is inseparably connected to the innovative concept of emulation and reproduction of biological sensorimotor systems and artificial neurobotics. Here, we report for the first time principally new artificial bioinspired optoelectronic sensorimotor system for the controlable immitation of opto-genetically engineered neurons in the biological motor system. The device is based on inorganic optical synapse (In-doped TiO nanofilm) assembled into a liquid metal (galinstan) actuator. The optoelectronic synapse generates polarised excitatory and inhibitory postsynaptic potentials to trigger the liquid metal droplet to vibrate and then mimic the expansion and contraction of biological fibre muscle. The low-energy consumption and precise modulation of electrical and mechanical outputs are the distinguished characteristics of fabricated sensorimotor system. This work is the underlying significant step towards the development of next generation of low-energy the internet of things for bioinspired neurorobotic and bioelectronic system.
下一代生物和纳米电子学的发展与生物感觉运动系统和人工神经机器人的创新模拟和复制概念密不可分。在这里，我们首次报告了一种主要的新型人工仿生光电感觉运动系统，用于在生物运动系统中可控地模拟光遗传学工程神经元。该装置基于组装成液态金属（镓铟锡）执行器的无机光突触（掺铟 TiO2 纳米薄膜）。光电突触产生极化的兴奋性和抑制性突触后电位，以触发液态金属液滴振动，然后模拟生物纤维肌肉的扩张和收缩。低能耗和电、机械输出的精确调制是所制传感器系统的显著特点。这项工作是朝着开发用于仿生神经机器人和生物电子系统的下一代低能耗物联网迈出的重要一步。
