Contact Microphone PVDF Stethoscope

contact mics act as transducers which pick up vibrations and convert them into a voltage which can then be made audible. They are widely used by musicians, audiophiles, and folks that just like to hear what most everyone else misses completely. The Stethoscope is my favourite, as it amplifies the bodies sounds such as heartbeat, bloodflow, bone and joint movements and even lungs. Most amazing invention hands-down.
Sensitive and robust, this active stethoscope features a small metal and rubber button head with a preamped PVDF film sensor inside. Five feet of shielded cable run from the head to the power module which terminates in a mono ¼" female output. The unit runs on a single 9 volt battery (included) and is designed to switch off when the output is unplugged.
Extremely low-noise and wide bandwidth (8 – 2 200Hz) make it ideal for recording body sounds such as the heart, blood and lungs. Can also used as a bone conducted pickup or a regular contact microphone or vibration sensor. For most applications you will require the use of a hi-fi or guitar amplifier. Attach sensor with medical tape or stretchy gauze.
