Batteryless sensors in building automation by use of wireless Energy Harvesting

In RFID applications the use of the electromagnetic field for the power supply of transponders is state-of-the-art. In the context of this presentation the use of the electromagnetic energy for the operation of sensor modules will be discussed. Based on the question, if the omnipresent radiation from the power supply network and from radio transmitters and mobile phone base stations is useable (Energy Harvesting), the feasibility for the operation of self-sufficient sensor modules especially for the use in the building automation area is explained. Additional conditions of this applications (operating range, measured variable) and technology (antennas, frequencies) are considered.

Radio Frequency Powering of Microelectronic Sensor Modules

Abstract In RFID applications the power supply of transponders via electromagnetic field is state-of-the-art. In this presentation the use of electromagnetic energy will be discussed for the operation of sensor modules. Starting with the question, whether the omnipresent radiation from power supply networks, radio transmitters, and mobile phone base stations is useable (energy harvesting), the feasibility of the operation of self-sufficient sensor modules is explained. Ancillary conditions of typical applications (e. g. operating range) and technology are considered. Zusammenfassung In RFID-Anwendungen ist die Nutzung eines elektromagnetischen Feldes zur Versorgung des Transponders etabliert. Im Rahmen dieses Artikels wird die Nutzung des elektromagnetischen Feldes für den Betrieb von Sensormodulen diskutiert. Ausgehend von der Frage, ob die allgegenwärtige Umgebungsstrahlung vom Stromnetz sowie Radio- und Mobilfunkstrahlung nutzbar sind (Energy Harvesting), werden die Möglichkeiten zur Versorgung autarker Sensormodule erläutert. Dabei finden Randbedingungen aus typischen Anwendungen (Reichweite, Messgröße) und der Technologie (Antennen, Frequenzen) Berücksichtigung.
