piezo heartbeat
Hello
My next project happens to be a Heartbeat monitor.I am looking for the sensors.What I have in mind is something like a piezo electric transducer normally used in such medical equipments.I have seen it but not able to locate that piece.Can anybody suggest a possible sourse,if possible in India?
That transducer picks up heartbeating sound when placed close to chest and then that audio peaks are converted into pulsus and counted.So what are the suggessions for a possible front end amplifier for that piezo sensor? The audio has to be amplified filtered and should be audible throutgh a speaker. or can you suggest the best possible sensor for this purpose? the stage have to be very sensitive because such commercial products are and should be able to detect the heart beat of foetus inside the utreus.
