Kibble balance: Redefining our understanding of weights
The Kibble balance is an electromechanical balance that can self-calibrate and measure mass, using electrical parameters. It operates in two modes: the force mode (static or weighing mode) and the velocity mode (dynamic mode). It is based on the principle of measuring the mechanical power of a force in terms of the electrical power needed to counteract it.
