Changing our habits for the better:

PULSE is a 3D-printed wearable device that pulses, or vibrates, when a person’s hand is nearing their face. The haptic feedback from a vibration motor simulates a nudge, reminding the wearer to avoid touching these entryways in order to reduce potential infection. As health officials advised the world to continue washing our hands, social distancing, and wearing a face mask when going outside, a team of three at NASA’s Jet Propulsion Lab (JPL) developed PULSE, to stand side-by-side with these efforts to keep us as healthy as possible.

PULSE is a simple and affordable technology that can easily be reproduced by anyone regardless of their level of expertise. A list of parts, STL files, and assembly instructions are all available as Open Source. We hope individuals or companies will replicate, refine or enhance PULSE and make it easily available for distribution.
