Micro sensors that communicate by RF are used to monitor the operating conditions in a wide range of applications. They offer the benefit of high flexibility, low costs and availability of online data. The use of new components allows extremely small sizes and enables ultra-low power operation with long battery life or even battery-free operation with power harvesters.
Fraunhofer ENAS focuses on the development of sensor networks for the application in the high and medium voltage range as well as for smart farming. Power harvesting from the electric or magnetic fringing field of the electric power lines enable self-sufficient operation when the sensor is attached to overhead power lines or to cables, cable joints or other equipment. The use of printing technologies for the production of electric components, component carriers and batteries and the use of compostable materials enable particularly cost-effective sensors for the monitoring of growth conditions in plant production.
