Tactile sensing
for soft robotic fingers.
A mass-producible 3D fingertip built for a tactile-sensing system that enables vision-free object recognition.
The system
Turning deformation into signal.
The work paired compliant fingertip geometry with a magnet-on-Hall-sensor approach. The research focused on mechanical compliance, repeatable fabrication, and validating how the fingertip responded under contact loading.
