|Project Title:||Energy Harvesting RFID Sensor and BLE Device for Autonomous Wireless Sensor Systems|
|Hosting Institution:||LSCM R&D Centre (LSCM)|
|Abstract:||With rapid development of electronic technology, sensor technology, micro electronic technology and wireless communication technology, wireless sensor system has become a trend of IOT (Internet of Things) applications and logistics applications.
One of the most important factors related with wireless sensor application is the power source for sensors and the supporting circuit. Lifetime of wireless sensor is limited by the capacity of battery in most application cases (depending on the power consumption of sensor structure, it may vary from several hours to several years). Battery depletion may lead to battery recharging, battery replacement or sensor discard. Therefore, limited battery energy may contribute a lot to maintenance cost of wireless sensor system or even make it impossible to use in many cases, especially for an inaccessible sensor application scenario.
As an emerging technology, energy harvesting is a promising solution for wireless sensor energy. In consideration of lower power consumption, RFID (Radio Frequency Identification) and BLE (BlueTooth Low Energy) are most likely to be used as wireles communication methods for energy harvesting sensor.
Compared with normal wireless sensors, energy harvesting wireless sensors have different enabling technologies and application scenarios. An energy harvesting RFID sensor or BLE device, ideally has unlimited lifetime and don’t need battery replacement for an autonomous wireless sensor system.
This project focuses on research and development of energy harvesting RFID senor and energy harvesting BLE device. A demo energy harvesting wireless sensor system will be designed based on the prototypes of energy harvesting RFID sensor and BLE device.
