Abstract: A wireless force sensor includes a flexible structure supported opposing a rigid structure with a gap between the flexible structure and the rigid structure. Contact traces on opposing surfaces of the flexible structure and the rigid structure form transmission lines. The contract traces are aligned to contact when a force is applied the flexible structure to cause contact between the traces on the opposing surfaces. Radio-frequency switches modulate a reflected signal from the transmission lines. An antenna receives an interrogation signal transmits the reflected signal.

Abstract: A preferred embodiment provides a deformable passive force sensor that induces a change in an interrogation RF signal present on a conductive connection to produce a changed reflective signal and an ID circuit that responds with an ID and the changed reflective signal.

Abstract: A vine robot catheter device includes an elongate outer catheter dimensioned according to a path to reach a region of a targeted anatomy, an inverted vine robot extension having its proximal end attached to the outer catheter and its distal end partially or fully inverted into itself within the outer catheter during delivery to a target site, and a fluid path in the outer catheter to apply fluid pressure to the vine robot extension to actuate the vine robot extension to evert and extend the distal end out of and beyond the outer catheter.
