Patent application numberDescriptionPublished
20120007469METHOD AND DEVICE FOR VIBRATION HARVESTING VIA GASFLOW - A method and device for gasflow, e.g. airflow, energy harvesting is disclosed. In one aspect, the device includes a cavity resonator such as a Helmholtz resonator which has a membrane for converting gasflow in vibration. The device may further include a vibrational energy harvester for converting the converted vibration into electrical energy. The device for gasflow energy harvesting is adapted such that the movement of the vibrational energy harvester is decoupled from the movement of the membrane. This allows to obtain a good output power of e.g. more than about 10 μW.01-12-2012
20120030486POWER MANAGEMENT SYSTEM FOR WIRELESS AUTONOMOUS TRANSDUCER SOLUTIONS - An autonomous transducer system is disclosed. In one aspect, the system includes an energy scavenging module, energy storage module, a load circuit having at least one functional block providing a given functionality, and a power management module arranged for providing power supplied by the energy scavenging module to the load circuit or for exchanging power with the energy storage module. The power management module may further include a tuning module configured to tune the at least one functional block of the load circuit according to a given configuration scheme.02-02-2012
