RF Energy Harvesting System for IoT Sensors

I&T Solution RF Energy Harvesting System for IoT Sensors
(REF : S-0998)
Matched I&T Wish
Trial Project
Solution Feature
  • Multiport and multiband antenna will be developed to collect ambient RF energy.
  • Multiport and multiband rectifier will be utilized to convert RF power into dc power. DC combining will be adopted to improve dc output voltage.
  • Power management unit (PMU) is used to incorporate multiple input power and redistribute them to multiple output loadings. Supercapacitor will be used to store up energy continuously.
  • Low duty cycle and low power sensors can be powered up from ambient RF energy harvesting.
  • Measured data can be transmitted to gateway via Bluetooth Low Energy (BLE).
Trial Application and Expected Outcome
  • Target volume of the entire RF energy harvesting system for IoT sensor is less than 200x180x40mm3.
  • Target frequencies and RF bands to be covered are 900MHz, 1800MHz and 2100MHz.
  • Possible IoT sensor types are for measuring different physical quantities in the environment, such as humidity or temperature.
  • The proposed system can be used indoors closed to cell phone repeaters. Data collection frequency is 1~4 times per day.
  • Base station compatibility is for any device compatible with Bluetooth 5.0.
