The Free-Standing Harvester (PMG FSH) from Perpetuum Ltd., Southampton, U.K., combines electromagnetic vibration energy harvesting technology with a selectable suite of energy charge, storage, and management options. The harvesters convert unused mechanical vibration into useable electrical energy to power wireless sensor systems used to monitor critical systems. The PMG FSH has integrated drive circuitry for charging an external storage device up to 4 mA at 5 V while reporting power levels via a serial communications interface via 3-pin IEC-standard connector. Output is up to 20 mW. The SS PMG FSH mounts either using a magnetic mount or a center throughhole. Intrinsically safe, certified versions are available, carrying ATEX and IECEx certifications; CSA certification is pending.
