Abstract
A pressure-sensing module includes: a circuit board having a first surface and a second surface opposite and parallel to each other, multiple elastic members electrically, and multiple piezoresistors. A first piezoresistor and a second piezoresistor are located on the first surface. A third piezoresistor is located on the second surface, one terminal is connected to the first elastic member and the other terminal is connected to the second elastic member or a fourth elastic member, so as to form a first channel. A fourth piezoresistor is located on the second surface, one terminal is connected to the third elastic member and the other terminal is connected to the fourth elastic member or the second elastic member, so as to form a second channel. The first channel and the second channel intersect or are connected to form a bridge circuit.
