Heart Spark

This heart-shaped pendant necklace visualizes the wearer’s heart beat in different light patterns. Heart beat is picked up from a commercial chest strap worn by athletes and wirelessly transmitted to the pendant. A microcontroller on the pendant translates the signal into a light pattern of the wearer’s choosing. Get one for yourself through Sensebridge’s Heart Spark page.

Heart Spark and my sound illuminating dress were in the eTextile and Wearable Computing Showcase at Maker Faire on Saturday, May 21, 2011.
