A sensor assembly, comprising:
- a flexible body;
- and
- fiber Bragg grating (FBG) sensors disposed inside the flexible body,
- wherein the FBG sensors each comprise an optical fiber extending axially with respect to the flexible body, and lattices disposed in the optical fiber,
- wherein the FBG sensors comprise a force-detecting FBG sensor, and
- wherein a front end of the force-detecting FBG sensor protrudes from a front end face of the flexible body such that a lattice of the force-detecting FBG sensor is exposed.
A sensor assembly, comprising:
