A transducer element particularly adapted for use in an apnea detection system is formed of resilient conductive material having an electrical impedance which varies in response to breathing movement of an infant. A control detects the varying impedance and generates an alarm signal whenever variations caused by breathing movements fall below a predetermined level.
