The ANU said this meant they had taken one more step on the journey to collect renewable or ambient energy from mobile phone base stations which could be used to power battery-operated wireless sensors.
Such sensors have multiple uses in industries, with health and agriculture being two examples.
Lead researcher Dr Salman Durrani from the ANU Research School of Engineering said wireless sensors for buildings, biomedical applications or wildlife monitoring used batteries that were tough to replace.
Australian viticulturists use sensors to keep track of temperature, wind speed, light, humidity and the amount of water in soil to boost the growth of grapes and prevent crop loss due to heat or cold.
Sports also use wireless sensors to collect performance data from participants. And, sensors are also used to keep track of the condition of bridges and machinery.
The scientists found that it was possible to use energy from solar or surrounding radio frequency sources, like communication towers or other mobile phone base stations, to replace batteries.
The delay in communication was generally less than a few hundred milliseconds.
Though the use of the technology was probably years away, Dr Durrani said the team had tacked an important practical consideration.
"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," he said.
