Finding the right sensor
Welcome and Thank You for considering my Title.
I am in the process of designing an electronic device that aims to counting the number of beats of someone's heart.
I will be using a BS2 microcontroller.
My plan is to find a sensor, compatible with the Parallax Basic Stamp microcontroller, that can sense very slight changes in pressure/vibrations; I also want to be able to calibrate it so that I can set it to respond only within certain peaks of pressure/vibrations.
I know that finding the right sensor for my project is paramount to making it work.
I want the sensor to be able to capt vabrations changes by direct contact with the skin---as it will be placed in contact with the leftmost side of the chest ( unless your heart is situated on the right side!!! )
.
I browsed through the sensors available on the site, but I am perplex about the vibration sensors available; cost effectiveness is a goal of mine as well.
Knowing that your suggestions matter, great already is my thankfullness to you; for I know you will provide me with some help.
Thanks.

How do I make it send a voltage to the I/O pin of the Basic Stamp only when the heart is contracting?
when the heart is relaxing, there will still be some vibrations sensed by the piezo; I do not want it to send a voltage signal when the heart is relaxing.
how do I make it respond only during contraction?
Thank you for your sharing of knowledge.
Thanks to any other who contributes abundantly to making this forum what it is.
