“The ones featured here all store data for four people and use bioelectrical impedance, a low level current that travels through a user’s body to gauge the amount of muscle and fat.”
“To measure body fatness, one may use dual energy x-ray absorptiometry, densitrometry or bioelectrical impedance.”
“Similarly, neurofeedback signals a convergence of psychiatry and neurology in bioelectrical approaches to treating affective disorders.”
