▎ 摘　　要

NOVELTY - The sensor has a sensing element configured to simulate a sensing element of a crack structure of a scorpion seam sensor, for detecting a strain signal. The crack structure of the sensing element detects vibration signals. A packaging layer is covered on the sensing element. An isolation layer is placed between the packaging layer and the sensing element, for isolating the packaging layer and the sensing element. The isolation layer generates a cavity between the packaging layer and the sensing element. A sensor main body detects a pressure signal and restores the pressure signal in a certain strain range. A conductive layer is arranged on a sensing substrate of the sensing element. The conductive layer is made of carbon black, carbon nano-tube, and graphene nano-tube. USE - High performance bionic paper based sensor for detecting a signal under severe environments e.g. underwater, wet and high temperature, in various advanced mechanical devices and systems. ADVANTAGE - The sensor is easy to process, and has high sensitivity, better stability, small volume and high economical efficiency. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) a method for detecting a signal based on a high performance bionic paper based sensor; and (2) a method for preparing a high performance bionic paper based sensor. DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional view of a high performance bionic paper based sensor.
