electromagnetic harvesting device by dennis siegel
storing the charge onto typical batteries, the special devices are capable of tapping into several electromagnetic fields to exploit their energy supply.

the omnipresence of electromagnetic fields is implied just by simple current flow. we are surrounded by electric charges which are produced for information transfer or as a byproduct. being capacitive, these fields can be harvested with coils and high frequency diodes.
in response, bremen-based designer dennis siegel built special devices that are able to tap into several electromagnetic fields to exploit them, where the energy is stored in typical batteries. users can then retain the charges from the power supply of a coffee machine, a cell phone or the catenary of a train by holding the harvester directly into the electromagnetic field whose strength is indicated by a LED on the top of the object.
harvesting the electromagnetic field of the cell phone
there are two types of devices for different electromagnetic fields: a smaller harvester that is suitable for lower frequencies below 100Hz which can be found in the general mains (50/60Hz, 16,7Hz) and a larger variation that is suitable for lower and higher frequencies like radio broadcast (~100MHz), GSM (900/1800MHz) up to bluetooth and WLAN (2,4GHz).
