What are Force Sensing Resistors? Force Sensing Resistors (FSR) A Force Sensing Resistor (FSR) is a printed functional ink applied to a thin material whose resistance changes when a force is applied to it. The force can be a mechanical load, a pressure or physical action. Force Sensing Resistor can also be known as a “force-sensitive resistor”. FSR is a variable resistor, constructed of several thin flexible layers and conductive inks that are applied using a precision screen printing process. These layers vary in resistance as pressure is applied and released. As pressure is applied, the resistance lowers and then returns to its original value as the pressure is removed. An FSR’s main purpose is to measure the force applied to a specific area and then relay that information via selected output electronics. FSRs typically use high-resistance, carbon-based inks which, along with other design factors, can be re-formulated to alter the functionality. Force Sensing Resistors can be designed as single-zone FSRs, Matrix Arrays, Discrete Arrays, Resistive XYZ (Digitizer) Pads, and Linear Potentiometers. Single-Zone ShuntMode™ and ThruMode™ FSRs There are two basic FSR configurations: the ShuntMode™ and the ThruMode™. ShuntMode Force Sensing Resistor: Consist of printed silver inter-digitated fingers that are shorted (“shunted”) by a printed FSR carbon layer.

什么是力感应电阻？

力感应电阻器（FSR）

力感应电阻器（FSR）是一种印刷的功能性墨水，应用于薄材料，当施加力时，其电阻会发生变化。力可以是机械载荷，压力或物理作用。力感应电阻也可称为“力敏电阻”。 FSR是一种可变电阻器，由几个薄的柔性层和导电油墨构成，使用精密丝网印刷工艺进行涂覆。当施加和释放压力时，这些层的电阻变化。当施加压力时，电阻降低，然后在压力消除后恢复到其原始值。 FSR的主要目的是测量施加到特定区域的力，然后通过选定的输出电子设备传递该信息。 FSR通常使用高阻碳基油墨，与其他设计因素一起，可以重新配制以改变功能。力感应电阻器可以设计为单区FSR，矩阵阵列，离散阵列，电阻XYZ（数字化仪）焊盘和线性电位计。

单区ShuntMode™和ThruMode™FSR

有两种基本的FSR配置：ShuntMode™和ThruMode™。

ShuntMode力感应电阻器：

由印刷的银色交叉指状物组成，通过印刷的FSR碳层短路（“分流”）。
可以通过更线性的输出检测更宽范围的力。
由于较少的印刷步骤和减少的油墨用量，通常成本较低。
ThruMode力感应电阻器：

更容易接受更轻的力量
不限于与ShuntMode的叉指银指相同的打印限制，因此允许更小的形状因子
需要更多的银和碳墨水，从而使它们更昂贵。
在众多应用中，一些常见的力传感电阻器用途包括：

上/下和强制/速度控制
乐器控制器
输液泵
足病学足门分析
电机/工具速度控制
机器人手指提示
座椅/床占用检测
库存控制
