Title: FRICTION PRESSURE SENSING CABLE AND MANUFACTURING METHOD THEREFOR
Abstract:
Provided is a friction pressure sensing cable. The friction pressure sensing cable comprises a central conducting wire, a high-molecular polymer insulation layer, an electrode layer, and an insulation outer layer all coaxially attached in sequence. The central conducting wire and the high-molecular polymer insulation layer, and/or the high-molecular polymer insulation layer and the electrode layer separately generate signals by the means of friction. The central conducting wire and the electrode layer are output electrodes of the friction pressure sensing cable. Also provided is a method for manufacturing the friction pressure sensing cable. The method comprises the following steps: (1) preparation of a high-molecular polymer solution; (2) formation of a poured hollow cavity framework; (3) pouring; (4) molding; and (5) formation of an insulation outer layer, so as to obtain the friction pressure sensing cable. Also provided are a friction pressure sensing cable for which high-molecular polymer insulation layer is modified, and a manufacturing method therefor. The provided friction pressure sensing cable can achieve a monitoring effect same as that of a conventional pressure cable, without requiring a high input impedance circuit or a charge-amplifier.
