Traditional myoelectric setups rely on single-point, dual-site control.
To work, sensors must sit precisely on the thickest part of the muscle belly.
However, in cases in which patients with:
✅ Short residual limbs
✅ Above-elbow amputations
✅ Heavy scar tissue
✅ Skin grafts or burns
✅ Deep soft tissue damage
✅ Weak muscle isolation
✅ Long-term muscle atrophy
👉 The challenge is that clinicians often only have a few viable electrode positions available.
👉 A minor socket rotation or placement shift of just 1-2 cm can drop signal amplitude by 20% to 50%.
👉 In difficult limbs, a large portion of fitting time may be spent simply trying to locate stable signals.
To fix this, clinicians invest in handheld signal probes or desktop software to speed up evaluation.
But these tools only mask the root cause.
👉 Even if a technician maps a "perfect" motor point and that position becomes completely fixed the moment electrodes are permanently embedded inside the prosthetic socket.
👉 When the patient returns home, normal biological changes like daily volume fluctuations, sweat, skin impedance shifts, or socket slipping (pistoning) immediately displace the fixed sensors from those precise muscle bellies.
The clinic is then pulled right back into a cycle of troubleshooting visits and socket refabrications.
What if we could completely decouple the sensing interface from the physical socket structure, eliminating the need to hunt for hyper-specific single points altogether?
