Shape sensing of miniature snake-like robots using optical fibers [PDF]
, 2017 Snake like continuum robots are increasingly used for minimally invasive surgery. Most robotic devices of this sort that have been reported to date are controlled in an open loop manner. Using shape sensing to provide closed loop feedback would allow for

BodySpace: inferring body pose for natural control of a music player [PDF]
, 2007 We describe the BodySpace system, which uses inertial sensing and pattern recognition to allow the gestural control of a music player by placing the device at different parts of the body.

Shape-sensing by self-sensing of shape memory alloy instruments for minimal invasive surgery
at - Automatisierungstechnik, 2023 Abstract Shape memory alloy-based flexible instruments have potential for enhancing the safety in minimally invasive surgery compared to passive rigid devices. We developed a data-driven polynomial model to estimate deflection of a 2D bending actuator using electrical resistance.

Towards shape-sensing using time-expanded ΦOTDR
European Workshop on Optical Fibre Sensors (EWOFS 2023), 2023 Optical fiber sensors are becoming a prominent solution to perform shape sensing thanks to their interesting and well-known advantages such as flexibility, lightweight, sensitivity, etc. However, the different approaches commonly used to date, which include fiber Bragg gratings, OFDR or OTDR architectures, are not able to achieve a fully distributed ...

Shape Sensing of a Complex Aeronautical Structure with Inverse Finite Element Method
Sensors, 2021 The inverse Finite Element Method (iFEM) is receiving more attention for shape sensing due to its independence from the material properties and the external load. However, a proper definition of the model geometry with its boundary conditions is required,
