To see if bone could transmit digital signals over longer distances – to a headset, say, from a sensor worn on the wrist – the team applied a small vibrator to various parts of the body. When they then measured the acoustic signals received elsewhere on the body, they found that a “frequency shift keyed” (FSK) signal gave the best distinction between 0s and 1s. In FSK signalling a 0 is represented by one frequency and a 1 by a different one.
