The Working Principles of Capacitors

Before delving into the applications of capacitors in wearable health monitoring, it is essential to understand their working principles. A capacitor is an electronic component that stores and releases electrical energy. It consists of two conductive plates separated by an insulating material known as a dielectric. When a voltage is applied across the plates, an electric field is created, causing positive and negative charges to accumulate on the respective plates. This accumulation of charges results in the storage of electrical energy.

The capacitance of a capacitor, measured in farads (F), determines its ability to store charge. A higher capacitance value indicates a greater charge storage capacity. Capacitors can be classified into various types based on their dielectric material, such as ceramic, electrolytic, tantalum, and film capacitors. Each type has its own unique characteristics and applications.
