WISP stands for '''Wireless Identification and Sensing Platform'''. The term "Identification" comes from "[[Radio Frequency Identification]]" (RFID). WISPs have the capabilities of RFID tags, but also support sensing and computing. Like any [[passive]] RFID tag, WISP is powered and read by a standard off-the-shelf RFID reader, harvesting the power it uses from the reader's emitted [[radio]] [[signals]]. To a RFID reader, a WISP is just a normal EPC gen1 or gen2 tag; but inside the WISP, the harvested energy is operating a 16-bit general purpose microcontroller. The microcontroller can perform a variety of computing tasks, including sampling sensors, and reporting that sensor data back to the RFID reader. WISPs have been built with light sensors, temperature sensors, and strain gauges. WISPs can write to flash and perform cryptographic computations. The WISP is developed by [[Intel]] [[Research]] [[Seattle]]. |

WISP stands for Wireless Identification and Sensing Platform. The term "Identification" comes from "Radio Frequency Identification" (RFID). WISPs have the capabilities of RFID tags, but also support sensing and computing. Like any passive RFID tag, WISP is powered and read by a standard off-the-shelf RFID reader, harvesting the power it uses from the reader's emitted radio signals. To a RFID reader, a WISP is just a normal EPC gen1 or gen2 tag; but inside the WISP, the harvested energy is operating a 16-bit general purpose microcontroller. The microcontroller can perform a variety of computing tasks, including sampling sensors, and reporting that sensor data back to the RFID reader. WISPs have been built with light sensors, temperature sensors, and strain gauges. WISPs can write to flash and perform cryptographic computations. The WISP is developed by Intel Research Seattle.
Implementation
The WISP consists of a board with power harvesting circuitry, demodulator, modulator, microcontroller, external sensors, and other components such as EEPROM and LED.
Applications
Wisps have been used for light level measurement, acceleration sensing, cold chain monitoring (passive data logging), and cryptography and security applications.
