The Pulse Sensor is a plug-and-play ready component that hooks up to the Arduino platform which opens a ton of possibilities to incorporate biometric data into wearable electronic designs thanks to it’s very small form factor.
The creator of the Pulse Sensor, Joel Murphy and Yury Gitman, set up a Kickstarter account to get the necessary funding and move that great idea from prototype stage into mass produced, open source reality.
The Pulse Sensor works similar to a optical heart-rate pulse sensor, picking up the blood flow rate, preferable on a ear lobe or finger tip, via photodiode. It is not intended to be of medical grade accuracy but still – it gives highly reliable values according the the duo’s own testing.
With just 1/2 inch in diameter (about 12mm), looking like a piece of jewelry and having two holes to sew the button shaped Pulse Sensor to fabric, this little bugger is inviting itself for an easy integration into wearable tech designs that react and act in sync with the heart beat of the wearer.
You can find all the details about the Pulse Sensor on Kickstarter and on The Pulse Sensor home page. If you want to be one of the first to get your hands on the Pulse Sensor – you can still pledge your contribution to the already well funded project until Sept 7 and get the Pulse Sensor Kit including Software & Source Code, PDF User-Guide, and a “Special Thanks” on PulseSensor.com
