Abstract
一种力感应装置,其包括刚性结构(10)与力传感器(R1、R2、R3、R4),刚性结构(10)包括间隔设置的刚性块(11),相邻两个刚性块(11)之间形成应变放大区(12),四个力传感器(R1、R2、R3、R4)以两个为一组,两组力传感器选择性地对应设置于应变放大区(12)的其中两个安装面,该四个力传感器(R1、R2、R3、R4)连接形成不同的电桥电路。在使用时将刚性结构(10)贴合在被测物体上,不同电桥电路电连接于信号处理电路,进而分别检测刚性结构(10)在不同方向上的形变并得出被测物体对应方向的作用力。该力感应装置为一体式结构,容易安装,电路简单,低成本。该力感应装置、力感应方法及具有该力感应装置的设备,可以非常灵敏地检测被测物体在多维度方向上的微小形变,精准识别压力。
