World first from Arveni

Arveni, based in France, claim to have developed the world's first batteryless device powering a bidirectional radio. This has been developed to power an infrared remote control. The device uses a powerful piezoelectric microgenerator, which delivers up to 90mW (for the first transmission in infrared). Arveni also integrated a low power radio based on IEEE 802.15.4 standard. This radio features 'bidirectional communication' - ideal for point to point applications where the user wants to know if his command has been received correctly. In this case, Arveni has added an LED onto the remote control, that lights when the acknowledgement of receipt of the receiver is received by the remote control. The LED is also powered by the microgenerator.
Arveni will be demonstrating the 12 button wireless and microgenerator powered remote control at the Hannover Fair and at the IDTechEx Energy Harvesting & Storage event in Munich, Germany on May 26-27 ( This demo is based on the 802.15.4 bidirectionnal radio, and is pictured.
Arveni CEO Jean Frederic Martin says, "This energy harvesting device delivers more than 10 times more energy than harvesters from most others and only Arveni with 9 patents specific on piezo energy harvesting, has the capability to power such applications."
