    • A strain sensor, a system for monitoring a state of a battery cell, and a battery including the strain sensor. The strain sensor includes a thin, flexible substrate, a plurality of piezoresistors mounted on the substrate, an input for receiving a voltage signal, an output for providing an output voltage signal from the plurality of piezoresistors. The plurality of piezoresistors are connected to form a circuit that is insensitive to a change in temperature and an in-plane deformation of the substrate. The system includes the strain sensor, a source of voltage, and an analysis module configured for receiving a voltage signal based on the output voltage signal provided at the output of the strain sensor and calculating a state of charge or a state of health of a battery cell based on the received voltage signal. The battery includes the strain sensor and a space for spacing adjacent battery cells.
    • 应变传感器,用于监视电池单元的状态的系统以及包括应变传感器的电池。 应变传感器包括薄的柔性衬底,安装在衬底上的多个压电电阻器,用于接收电压信号的输入端,用于提供来自多个压敏电阻器的输出电压信号的输出端。 多个压敏电阻器被连接以形成对温度的变化和基板的面内变形不敏感的电路。 该系统包括应变传感器,电压源和分析模块,其被配置为基于在应变传感器的输出处提供的输出电压信号接收电压信号,并计算电池的状态或电池的健康状态 基于接收电压信号的单元。 电池包括应变传感器和用于间隔相邻电池单元的空间。
