2results about How to "Implement pressure detection" patented technology

The utility model provides a catalyst pressure detection mechanism, which comprises a base, a pedestal is horizontally arranged on the base, a dredging piece is mounted on the pedestal, a cavity tool is placed on the dredging piece, a servo electric cylinder is arranged above the cavity tool, and a pressure sensor is arranged on the servo electric cylinder. The end part of a piston rod of the servo electric cylinder is connected with an extrusion head used for extruding and detecting the pressure of the pug in the cavity tool, and a pressure needle head used for detecting the pressure of the pug in the cavity tool is mounted at the bottom of the extrusion head. The device has the advantages that sample preparation and pressure detection of a catalyst material can be realized, and pressure detection during discharging of a simulated extruder can be realized at the same time.

This invention discloses a flexible pressure sensor, comprising a flexible upper substrate layer, a flexible lower substrate layer, a mesh upper electrode, a mesh lower electrode, and a flexible piezoresistive material. The flexible upper and lower substrate layers are made of fabric material with an adhesive layer. The mesh upper electrode extends along a first direction, and the mesh lower electrode extends along a second direction, with the two electrodes intersecting to form multiple intersection points. The flexible piezoresistive material is disposed at the intersection points. When pressure is applied, the contact area of ​​the mesh electrodes through the piezoresistive material increases, resulting in a decrease in resistance at the intersection points, thus achieving pressure detection. This invention utilizes a fully flexible fiber material for construction, achieving large-area pressure detection with a multi-point array distribution. It has the advantages of simple structure and low cost; the sensor can be bent, folded, and crumpled without affecting its performance.
