Bioelectrical impedance analysis (BIA) is a method for estimating body composition, in particular body fat and muscle mass, where a weak electric current flows through the body, and the voltage is measured in order to calculate impedance (resistance and reactance) of the body. Most body water is stored in muscle.
Bioelectromagnetics, also known as bioelectromagnetism, is the study of the interaction between electromagnetic fields and biological entities. Areas of study include electromagnetic fields produced by living cells, tissues or organisms, the effects of man-made sources of electromagnetic fields like mobile phones, and the application of electromagnetic radiation toward therapies for the ...
They may directly use mechanical power from muscles, or a generator may convert energy generated by the body into electrical power. Human-powered equipment primarily consists of electrical appliances which can be powered by electricity generated by human muscle power as an alternative to conventional sources of electricity such as disposable ...

Developmental bioelectricity is a sub-discipline of biology, related to, but distinct from, neurophysiology and bioelectromagnetics.Developmental bioelectricity refers to the endogenous ion fluxes, transmembrane and transepithelial voltage gradients, and electric currents and fields produced and sustained in living cells and tissues.
According to the U.S. Department of State, roughly 8 million metric tons of plastic go into the world's oceans every single year.Given that most plastics aren't biodegradable, they are likely to ...
Body capacitance was a significant nuisance when tuning the earliest radios; touching the tuning knob controlling the tuner's variable capacitor would couple the body capacitance into the tuning circuit, slightly changing its resonant frequency. Design of such circuits intended to be adjusted by a user must prevent interaction of the user's ...
In 1970, millions of Americans concerned about the environment observed the first 'Earth Day.' Forty-four years later, the tradition and message of conserving our beautiful planet is still going ...
