technical field [0001] The invention relates to the technical field of whisker sensors, in particular to an active bionic whisker sensor and a device. Background technique [0002] The tentacles sensor is a sensor manufactured by artificial bionics by simulating the working principle of the tentacles of mice, sea lions and other animals, and realizes the detection of the size, shape, orientation, texture and position of objects in complex environments. At present, the existing whisker sensors mainly include resistive, capacitive, electromagnetic, piezoelectric (PZT), photoelectric (Position sensitive detector, PSD) and nano triboelectric generator (TENG) methods. The volume of the traditional resistive whisker sensor can be made very small, but it is difficult to realize active detection, which limits the detection ability and application of the sensor; the capacitive whisker sensor is easily affected by the surrounding environment due to the capacitive working principle.

AI Technical Summary

Problems solved by technology

The volume of the traditional resistive whisker sensor can be made very small, but it is difficult to realize active detection, which limits the detection ability and application of the sensor; the capacitive whisker sensor is easily affected by the surrounding environment due to the capacitive working principle. The stability of the output detection signal is poor; the electromagnetic whisker sensor can achieve better signal output, and it is also difficult to achieve active detection, which limits the detection capability and application of the sensor; the piezoelectric whisker sensor relies on its own working principle , can realize displacement detection while actively driving the whiskers, and the sensor can be highly integrated, but affected by the small deformation capability of PZT and the hysteresis characteristics of electrical signals, the piezoelectric whisker sensor is mostly used to detect small deformation, rough It is difficult to simulate the real detection behavior of living things; the current research on the photoelectric whisker sensor is in a passive way, and it is mainly used for the detection of the shape of the object; The extrusion of the material leads to the redistribution of charges in the material, which forms the output of electrical signals. Since the detection process is easily affected by the charge distribution in the surrounding environment (for example, static electricity in the human body), it is difficult to popularize and apply
