    What is the easiest/cheapest way I could detect a heartbeat from outside a shirt? I am trying to make a small device that will detect a heart beat and then pulse an led.

    Thanks!

    I'm probably very wrong, but check a piezo sensor... They usually have low stress requirements..
    But i've never used one so don't take my word for it.
