ABSTRACT:
A hand-held massager capable of self-excited, impedance-matched vibration for optimal massaging of each particular body part of each particular individual. The massager includes a hollow, open-ended contact piece to which is coupled a vibrator and which is to be held against a desired body part. A pressure sensor is mounted to the contact piece for sensing pressure variations in the cavity in the contact piece while the open end thereof is held against the body part, in order to ascertain the mechanical impedance of that body part. A closed-loop, electropneumatic vibration control system makes it possible for the mechanical impedance to be fed back to the vibrator, causing the latter to make self-induced vibration. Thus the desired body part is optimally massaged at its resonance frequency.
