　　小型、新型汽车、自动化和医疗应用的力传感器解决方案

　　推还是拉？可能的话，如果是动作，而场是电子学，则需要一个力传感器。简单地说，力传感器是将机械力输入转换成电输出信号的传感器。压电式力传感器用于诸如冲击、高速压缩、振荡和张力等测量。

　　施加在传感元件上的力影响材料的原子结构，导致电荷和输出信号的分离。力传感器用于各种汽车应用，如刹车、气囊、速度控制、悬架和变速器。他们有广泛的医疗、游戏、工业和航空航天用途。

　　有许多类型的传感器测量力，传感器内的传感器检测事件的力量分为三大类：

　　应变计荷重传感器

　　压电晶体

　　通过压力的测量

　　应变式称重传感器是最常用的力传感器。应变计响应于所处的应变，而元件的形状和弹性则构成施加力产生的应变的大小。应变计包括电阻应变片、箔应变计、薄膜应变计、半导体应变计和金属丝应变计。应变计是用来测量静力的。

　　Piezoelectric crystal force transducers are used with a charge amplifier to integrate the electric charges formed on a crystal surface to a given and measurable signal proportional to the force applied. These sensors are unique in that they are active sensors that do not require a power supply， and signals are easily generated without causing geometric changes to the force measurement route. They have a high-frequency response capability that makes them suitable for dynamic measurement， but because of leakage of charge from the charge amplifier， also called drift， they cannot perform static measurements accurately. They have small dimensions and can operate well within a wide temperature range， and are typically used to measure oscillation， impact， and high-speed tension and compression.
