Projects:2014S1-38 Semi-Passive Wearable Sensors

Project Introduction

The WISP is a passive Computational RFID that harvests operating energy from, and communicates with, UHF RFID readers. It can also process data from its onboard sensors. We developed the new WISP which has extended functionality with its advanced accelerometer and barometer, SPI and I2C bus, and copper wire antenna. The new WISP provides a RFID-scale, fully programmable, battery-less sensing platform that executes programs on its MSP430 microcontroller. The hardware and software are both derived from the open source WISP 4.1DL wiki.

Project Information

The project aim is to prototype a new generation of semi passive sensors for monitoring vital statistics and human motion. This prototype which optimizes the WISP4.1 DL version, utilizes RFID technology, ultra-low power microcontroller, accelerometer and barometer sensor. This project also applies a new approach of WISP 5.0 which uses new generation of microcontroller MSP430FR5969.
