Cutaneous structure for mammalian might provide a solution for efficiently overcoming bottlenecks in artificial sensory system and an insight into eventually implementing a sensor comparable to the level of human sensation. In this talk, we propose the first sensor skin directly mimicking Piezo2 ion mechanotransduction channel expressed in touch mechanoreceptors - epidermal Merkel cells that are termination of touch receptive specializations in mammalian somatosensory system. The device architecture based on the hierarchically assembled ionic material operates in ultralow power consumption of 1mV, and shows remarkable sensitivity of 9nF/kPa at extremely small dimension. Furthermore, sensing range of artificial ionic mechanotransduction device unprecedentedly covers broad detecting pressure regime, including intelligent voice identification, human health monitoring, and even heavy measurement towards the realization of sophisticated human skin. |
