THEREMICRO/ TEREMINI is the nickname for the simplest type of capacitive sensor, that in the past has been given the name “theremin” (originally “termenvox” - by his inventor Lev Sergeyevich Termen). The invention goes hand in hand with the pioneering years of radio – electronic amplification - the 1920s. In fact, it is a cast-away of the development in the field of radio - namely: the heterodyne (frequency mixing) principle and the observation of the capacitive properties of human body. With termenvox, this usually undesirable effects were put to good use.

Termenvox is in essence a capacitive sensor that functions by comparing the frequencies of two oscillators. One of the oscillators is fixed and the other is coupled with the antenna to its surroundings. A human moving their hand acts as a capacitor to ground and adds themselves to the oscillating system. The closer the hand (or any part of the body) - the higher the total capacitance and thus the lower the oscillating frequency. The free-running frequency (no hand near the antenna) of this variable oscillator should ideally be the same as that of the fixed frequency oscillator - making the difference of these two frequencies equal to zero.
