Abstract
A pressure sensing device is provided. In the pressure sensing device, the rigid structure includes rigid blocks arranged at intervals, and strain amplification zones are formed between every two adjacent rigid blocks. The force sensors include first sensors and second sensors. The first sensors are arranged on the two installation surfaces of the strain amplification zones and capable of following the deformation of the measured object, the second sensors are arranged on the two installation surfaces of the rigid blocks and located close to corresponding first sensors. At least four force sensors are connected to form a bridge circuit, and the bridge circuit is electrically connected to a signal processing circuit, so as to detect deformation of the rigid structure and obtain a force acted on the measured object. An output signal of each of the second sensors serves as a temperature compensation signal of the corresponding first sensors.
