Abstract

The invention belongs to the technical field of sensors and particularly relates to a strain sensor, a method using the strain sensor to acquire high sensitivity and a strain measuring device comprising the strain sensor. The strain sensor comprises a flaky carrier and is characterized in that a first sensitive grid and a second sensitive grid are respectively arranged on two sides of the flaky carrier, and the projections of the first sensitive grid and the second sensitive grid on the flaky carrier do not coincide with each other. The method can double the sensitivity of the sensor and is convenient to operate. The strain measuring device has the advantages that the strain measuring device is compact in structure by using a FPC connector to connect with the strain sensor, the strain measuring device is simple to operate, convenient to use and capable of saving cost, and plug type electric connection with an external signal receiving device can be formed conveniently.
