Perpetuum, the world leader in vibration energy harvesting, announces its PMG17 vibration energy-harvesting microgenerator can readily be used to power the Texas Instruments CC2420 single chip RF transceiver and MSP430 16 bit ultra-low-power microcontroller. As a result, sensor node manufacturers can now design battery-free sensor systems using the IEEE 802.15.4 standard even for the most data intensive applications such as condition monitoring.

A vibration energy harvesting sensor node designed around the CC2420 by Perpetuum engineers is capable of sampling 2kbyte of vibration data and transmitting it over 100m (line-of-sight) every 60 seconds when only 0.025g of vibration is present. At this incredibly low level of vibration the PMG17 energy harvester produces up to 1mW, while at 1g the output is around 50mW, enabling the node to measure and transmit continuously. The node can be configured to measure and transmit much smaller data sets, such as temperature, more frequently or larger data sets less frequently, depending on the application.

An application note to aid engineers designing self-powered wireless condition monitoring systems is available for download from the Perpetuum website.
