It seems like wireless power transfer is all the rage these days. There’s wireless charging mats, special battery packs, heck, even some phones have it built in! And they all use inductive coils to ...

Variable capacitors may be useful, but the air gap that provides their capacitance is their greatest weakness. Rather than deal with the poor dielectric properties of air, some high-end variable ...

Another passive two-terminal electrical component is the capacitor. It is formerly known as a condenser and is capable of storing energy in the form of an electrostatic charge that produces a ...

A capacitor is a passive electronic component that stores electrical energy in an electric field. It consists of two conducting plates separated by an insulating material called a dielectric. When a ...

Touch sensors have been around for years, but recent advances in mixed signal programmable devices are making capacitance-based touch sensors a practical and value-added alternative to mechanical ...
