$$$ Simple design and lower cost $$$
No Magnetic field or AC current applied around the patient body.
Comfortable Belt:
Soft, non-constraining, washable, “one size fit all” belts.
Quality output signal:
Clean noise free output signal to bio-amplifier.
Linear output signal: The output signal is linear to body circumference change while breathing. Inspire signal on one belt and simultaneous expire on a second belt is readily measured; thus, there is no false paradoxing.
