TYRELESS - Integrated piezoelectric Energy Harvesting systems for smart truck tyre monitoring - # 73627-494298

本项目的目的是开发一个集成的TPMS传感器系统。这包括;a)动能收集元件（基于PVDF和/或陶瓷材料），b)能量存储元件（超级电容器）以及与c)电源管理和传感设备的集成。主动采集元件将由巴斯大学的Chris Bowen教授开发，并将与整流/电源管理芯片（由Linear Technologies提供）耦合，该芯片连接到恩智浦无线ARM Cortex M4处理器。早期原型将由EH/S元件以及压力传感MCU和RfID电路组成，能够在不连接轮胎的情况下远程中继数据。这项工作将包括制造和测试，以了解可以收集的功率，工作温度窗口和EH/S换能器的使用寿命。对于苛刻的环境，组件的强大集成始终是一个挑战，因此CPI将研究最佳的层压/连接技术，以最大限度地提高性能。

The purpose of the project is to develop an integrated TPMS transducer system. This includes; a) kinetic harvesting element (based on PVDF and/or ceramic materials), b) energy storage elements (supercapacitors) and integration with c) power management and sensing devices. The active harvesting element is to be developed by Prof. Chris Bowen at Bath University and will be coupled to a rectification/power management chip (supplied by Linear Technologies) which connects to an NXP wireless ARM Cortex M4 processor. An early stage prototype would consist of an EH/S element alongside a pressure sensing MCU and RfID circuit capable of relaying data remotely without connection to the tyre. The work would include fabrication and testing to understand the power that can be harvested, the operating temperature window and the lifetime of the EH/S transducer. Robust integration of the components is always a challenge for demanding environments, and so CPI will look into the best laminating/joining technologies to maximise performances.
