Current wireless sensors for buildings, biomedical applications or wildlife monitoring use batteries that are difficult to replace.
According to new findings by researchers in Australia, renewable or ambient energy from mobile phone base stations can be harvested to power battery-operated wireless sensors. Salman Durrani from Australian National University, who is leading the research says that the current wireless sensors for buildings, biomedical applications or wildlife monitoring use batteries that are often difficult to replace.
The team of researchers modeled that how much energy would a wireless sensor take to sense and transfer information. They are still working on ways to analyse the problem. Says Durrani, “A major problem hindering the widespread deployment of wireless sensor networks is the need to periodically replace batteries.”
Wireless sensors are used in various aspects of daily life, including usage to measure temperature, wind speed, light, humidity and soil moisture to optimize the growth of crops and sports to collect performance data from athletes. The team found it was feasible to replace batteries with energy harvested from solar or ambient radio frequency sources such as communication towers or other mobile phone base stations, with communication delays typically limited to less than a few hundred milliseconds.
“If we can use energy harvesting to solve the battery replacement problem for wireless sensors, we can implement long-lasting monitoring devices for health, agriculture, mining, wildlife and critical national infrastructure, which will improve the quality of life,” Durrani added in a paper published in the journal IEEE.
