Te Role Of Soft Sensors in Soft Robotics
Soft sensors are not merely miniaturized versions of their rigid contrparts; they y endigt a paradigm shift in how sensing is embedded into a machine. A soft robot that relies only on external visision or encoders strugles to capture the nuanced deformation and contact forces that govern its interaction the environment.

From Rigid to Compliant Sensing
Conventional robotic sensors - strain gaugs, load cells, and inertial measurement units - are typically rigid and brittle. When embedded in a soft matrix, they create stress concentrations that degrade both the sensor 's closiacy ande thee robot' s compleance.
