rethinking cardiac pacing with a miniature, wirelessly powered cardiac pacemaker designed to eliminate implanted batteries and reduce complications while delivering reliable, precisely timed pacing

why build this

pacemakers save lives

a healthy heartbeat depends on precisely timed electrical signals. pacemakers restore this rhythm and sustain life for irregular beats.

but most systems rely on implanted batteries and transvenous leads, which introduce long-term risks

batteries require replacement surgeries and leads can fracture, migrate, or cause infection

the concept

what if pacing didn't require batteries?

eliminating onboard batteries could dramatically extend device lifetime and reduce surgical intervention

small, simple, and implantable

by removing batteries and reducing system complexity, this fully wirelessly powered cardiac pacemaker supports safer, longer-term cardiac therapy
