Wireless charging allows an electric vehicle to be charged simply by parking it over a wireless charging pad containing an electrical coil. Vehicles can even be charged dynamically while driving along roads having multiple embedded coils. This works using the same principle as wireless phone charging or a transformer – electromagnetic induction. Induction is the…

Self-powered electronic devices that define the Industrial Internet of Things (IIoT) have special needs that can be addressed through the judicious selection of battery chemistry. SOL JACOBS | TADIRAN BATTERIES Going ‘truly wireless’ typically necessitates the use of primary (non-rechargeable) or rechargeable lithium-ion (Li-ion) batteries. Besides untethering applications from ac lines, use of rechargeable batteries […]

Small self-powered systems, including wireless sensors and small robots currently under development, can use triboelectric nanogenerators (TENGs) and piezoelectric nanogenerators (PENGs) as prime power sources. TENGs and PENGs offer large open circuit voltages, low materials cost, ease of fabrication, and good energy conversion efficiencies. TENGs use triboelectricity, commonly called static electricity, to convert common mechanical […]

Wireless applications that need continuous monitoring to save energy, detect unsafe or other avoidable conditions and need to avoid creating serious maintenance issues are prime candidates for energy harvesting.  Steam trap monitoring provides an excellent example of this type of batteryless sensing.  Roughly 20% of the steam leaving a typical facility’s central boiler plant in space […]
