本文介绍了无线识别和传感平台(WSAP)，这是一个可编程的无电池传感和计算平台，旨在探索传感器增强型射频识别(RFID)的应用。WISP使用16位超低功耗微控制器来执行传感和计算，同时只使用收集的射频能量进行操作。到目前为止，已成功集成到WISP平台中的传感器包括温度、环境光、整流电压和方向。微控制器将测量结果编码为符合电子产品代码(EPC)1类1代标准的ID，并动态计算所需的16位循环冗余校验(CRC)。最后，WIP模拟EPC协议将ID传递给RFID读取器。据作者所知，WIP是第一个完全可编程的计算平台，可以使用从远程(UHF)RFID读取器传输的电力来操作，并在单个响应分组中传递任意多比特数据。
This paper presents the Wireless Identification and Sensing Platform (WISP), which is a programmable battery-free sensing and computational platform designed to explore sensor-enhanced radio frequency identification (RFID) applications. WISP uses a 16-bit ultralow-power microcontroller to perform sensing and computation while exclusively operating from harvested RF energy. Sensors that have successfully been integrated into the WISP platform to date include temperature, ambient light, rectified voltage, and orientation. The microcontroller encodes measurements into an Electronic Product Code (EPC) Class 1 Generation 1 compliant ID and dynamically computes the required 16-bit cyclical redundancy checking (CRC). Finally, WISP emulates the EPC protocol to communicate the ID to the RFID reader. To the authors' knowledge, WISP is the first fully programmable computing platform that can operate using power transmitted from a long-range (UHF) RFID reader and communicate arbitrary multibit data in a single response packet.
