|a Developing highly sensitive strain sensors requires conduction pathways capable of rapidly switching between disconnection and reconnection in response to strain. Ion channels in living organisms exactly control the channel switch through protein-composed gates, achieving changeable ion currents. Herein, inspired by the gating characteristics of the ion channels, a programmable fluidic strain sensor enhanced by gating ion pathways through heterogeneous strain distribution of discrete micropillars is proposed. During stretching, the contraction and closure of the widthwise gaps between discrete micropillars greatly weaken or even nearly cut off the conduction pathway, resulting in orders of magnitude increase in resistance and thus ultrahigh sensitivity. By adjusting the combination form and structural parameters of the discrete micropillars in the fluidic channel, the sensitivity and strain range can be customized. Thus, a gauge factor of up to 45 300 and a stretch range of 590% are obtained. Benefiting from the fluidic gating mechanism, no mechanical mismatch can be observed at the interface, breaking through the sensing stability issue of flexible sensors. The proposed sensor can be used to detect the full range of human motion, and integrated into a data glove to achieve human-machine interaction
