Micro Power Generation
The coming decade will see the rapid emergence of low cost, intelligent, wireless sensors and their widespread deployment throughout our environment. A key issue for these wireless node designs is that they achieve high degrees of power-efficiency for autonomous, maintenance-free operation, where it is likely that nodes will require deployment for periods of years since the cost of battery replacement will be prohibitive and impractical. This can effectively be described as a “deploy and forget” scenario. In such a scenario, the ability to scavenge energy from the environment to power the system is highly desirable. The road map for micropower-nanomagnetics group is progressing from miniaturised vibration energy harvester to MEMS and NEMS based devices.
