Title:
LOAD SENSOR, LOAD DETECTION SYSTEM, AND LOAD DETECTION PROCESSOR
Document Type and Number:
Japanese Patent JP2019168231
Kind Code:
A
Abstract:
To provide a load sensor, a load detection system, and a load detection processor which can achieve a lowered unit cost with a simple configuration and are suitable for disposable application.SOLUTION: In a load sensor (1), conductive rubber (9) constituting a part of an antenna (3) is reversibly deformed by a load received from an object. The conductive rubber is composed of a rubber base material (9a) with a conductive material (9b) dispersed therein. Deformation of the conductive rubber changes at least either one of resonance frequency or radio field intensity of a reflected wave transmitted in response to a radio wave received from an outside. Reception signal intensity information of the reflected wave is measured and the load is detected on the basis of its output.SELECTED DRAWING: Figure 1
