Independence Pass is a wearable device I designed for Intel Labs that allows for the unlocking of personal compute devices based on proximity. The interesting differentiator that this wearble employs is what's called electro-impedence tomography. What this method allows for is essentially the mapping of a wearer's electrical imprint at their wrist which is in turn converted into a key/password that is calculated throughout the day for unlocking purposes. This device came in both eight and sixteen electrode configurations and all prototypes were produced via multi material 3D printing. For the prototypes, I also designed the experimental wiring apparatuses and electrode arrays for testing.
