The quality factor, also known as the Q factor, is a dimensionless parameter that describes how underdamped an oscillator or resonator is, and characterizes a resonator's bandwidth relative to its center frequency. A higher Q indicates a lower rate of energy loss relative to the stored energy, meaning the system is more selective in its frequency response and has a narrower bandwidth.
Wireless charging technology allows devices to be charged without direct cable connections by using electromagnetic fields to transfer energy. This technology enhances convenience and reduces wear on charging ports, making it increasingly popular in consumer electronics and electric vehicles.
The Qi Standard is a universal specification for wireless charging, developed by the Wireless Power Consortium, ensuring compatibility and efficiency across devices and chargers. It utilizes inductive charging technology, allowing devices to charge without physical connectors, promoting convenience and reducing wear and tear.
