Vibration powered impact recorder (VPIR)

机译:振动冲击记录仪(VPIR)

摘要

A vibration-powered impact recording device that harvests power from vibrations that affect the device is provided. The recording device is affixed to an object and includes a vibration limit detection and recordation system. The system can include a suitable part that is fixed to the object, and a mass (or other suitable part) that is less firmly attached, with the relative motion between the two parts producing an electrical voltage. The electrical voltage can be used to power an information storage unit that records the details of the impact and optionally other sensors which record other parameters such as temperature, humidity etc. at the time of impact.
