A novel energy harvesting technique that uses conducted electromagnetic interference as an energy source is presented. Conducted EMI generated from fluorescent light using a switched-mode power supply was measured and modeled as an equivalent voltage source.
This radiation occurs at discrete frequencies. Electromagnetic interference, EMI, occurs when a receptor is susceptible to a particular amplitude and frequency of transmitted source energy. Electromagnetic energy is generated in the form of spherical wave fronts, which travel in all directions from the source.
Electromagnetic interference (or EMI) is a disruption that affects an electrical circuit because of either electromagnetic induction or externally emitted electromagnetic radiation. EMI is the interference from one electrical or electronic system to another caused by the electromagnetic fields generated by its operation.
Communication devices are particularly susceptible to EMI. Unwanted radiation signals can cause system degradation or performance reduction, leading to serious damage and affecting safety if left unattended. The most prominent cause of EMI is an electrostatic discharge, which is commonly emitted from radios and televisions .
Interference due to emissions of EM waves from unshielded devices with the functioning of other devices is also called EMI or radio frequency interference. Electronic devices inhibit the capacity to emit and reduce susceptibility to EMI. Therefore a device must function in the presence of EMI from other devices, thereby exhibiting EM compatibility.
While taking great benefits and enhanced conveniences from these technological developments, we must realize that almost all transformative advances come with certain risks, which must be mitigated. One growing risk that threatens many aspects of society is electromagnetic interference (EMI).
