    • Sensors for monitoring shock or vibration of an object are provided. The sensors include a proof mass, at least piezoelectric device, and an electronic circuit connected to the piezoelectric device. The piezoelectric device generates a current when the proof mass imparts a force on the piezoelectric device in response to the proof mass being subjected to a transient acceleration when the object is subjected to a shock or vibration. The electronic circuit is at least partially controlled in response to the current generated from the piezoelectric device due to the shock or vibration. Embodiments of the sensor provide multi-axis sensing capabilities. Methods of making the sensors and flexible circuits are also provided.
    • 提供用于监测物体的震动或振动的传感器。 传感器包括至少是压电装置的检测质量块和连接到压电装置的电子电路。 当物体受到冲击或振动时,当证明物质响应于证明物质受到瞬时加速时,压电装置施加力而产生电流。 响应于由于冲击或振动而从压电装置产生的电流,至少部分地控制电子电路。 传感器的实施例提供多轴感测能力。 还提供了制造传感器和柔性电路的方法。
