Stimuli perception enables animals and robots to interact with unknown environments safely and predictably. For the sensing of soft robotics and wearable devices, although electronic skins have already been widely accepted and studied, their planar geometries are not applicable for multi-direction volume sensing. Herein, the innervation of sensing microchannel networks into elastic matrices to mimic the exteroception and proprioception of the human bodies is employed. Soft actuators with interlaced actuating and sensing microchannels resembling the distribution of muscle fiber and proprioceptors are fabricated and the internal stimuli perception of deformation configurations (bending, elongating, and bending directions) and magnitudes (bending angle and elongation) of the soft actuators are demonstrated. It is also demonstrated that a soft cubic sensor containing 3D microchannels (diameter: 400 µm) is capable of identifying 3D external stimuli, including force types (pressing, squeezing, shearing, and twisting) and real-time directions by measuring the resistance variation, and its application in the virtual reality field is exhibited.
