Is this trial a fit for you?
✓Likely a good fit
Ideal participants are generally healthy adults aged 18–90 who can walk about one mile comfortably and can attend weekly visits or wear the insoles at home for four weeks.
✕Probably not a fit
People who cannot walk a mile, are under 18 or over 90, have severe foot conditions preventing insole use, or are seeking therapeutic treatment rather than monitoring are unlikely to benefit.

What this trial studies
The project tests two generations of self-charging, medical-grade smart insoles and a companion mobile app to measure comfort, durability, and sensor accuracy. Phase 1 enrolls 10 subjects at the University of Utah for treadmill and campus walking tests using instrumented facilities; Phase 2 includes a 10-subject pilot at the University of Utah followed by a 100-subject, 4-week field study where participants wear insoles at home. The generation 2.0 device uses an improved energy harvester to increase on-device power for AI/ML edge computing. Data collection is observational: insoles record gait and physiologic signals while participants walk at different speeds and in daily life.
Why it matters
Potential benefit: If successful, the insoles could provide continuous, self-powered remote monitoring of gait and physiologic signals without frequent recharging, enabling earlier detection of mobility or health changes.
How similar studies have gone: Wearable insoles and remote monitoring devices have shown promise for gait and physiologic tracking in prior work, but combining self-charging energy harvesting with on-device AI/ML for prolonged, charger-free monitoring is relatively novel.
