Abstract: A bionic flexible actuator with a real-time feedback function and a preparation method thereof. The method includes: preparing stimuli-response layer and bionic flexible strain-sensor film layer, arranging bionic V-shaped groove array structure on bionic flexible strain-sensor film layer, and sticking bionic flexible strain-sensor film layer onto stimuli-response layer through adhesive layer; stimuli-response layer is prepared by adopting following steps: mixing multi-walled carbon nanotubes and polyvinylidene fluoride after being dissolved in a solvent respectively and obtaining a mixed solution; performing a film formation process to mixed solution and embedding a first electrode to obtain stimuli-response layer.

Abstract: A micro-vibration sensor and preparation method thereof. The method includes a metal sheet is coated with first curing material, and first curing material is cured into first cured layer; piezoelectric thin film element is attached to edge of first cured layer; one side, attached with piezoelectric thin film element, of first cured layer is vertically placed into second curing material, and second curing material is cured into second cured layer; and metal sheet is removed to obtain micro-vibration sensor. Due to fact that piezoelectric thin film element is arranged at a crack tip, during micro-vibration, stress in stress field of crack tip is rapidly increased due to crack stress deformation, and stress signal is efficiently converted into electric signal; and micro-vibration sensor has characteristics of being low in detection limit and high in accuracy.
