Battery-less NFC/RFID Temperature Sensing Patch


Design files


Battery-less sensor measurements that utilize energy harvesting from the RF field can be implemented in applications ranging from medical, health and fitness, and industrial where instantaneous measurements are required and a battery is not feasible or desired. This design implements a single chip NFC/RFID field powered temperature sensor system with the RF430FRL152H.

  • No batteries required
  • Single chip design ADC configuration is ""over the air""
  • Minimal external components
  • Different antenna configurations allow many form factors
  • This design has been tested and includes an application report, schematic/PCB design files and software.

Sample code described in this design can be downloaded from the design guide Design Guide: https://www.ti.com/lit/zip/slac692
