Continuum robots provide inherent structural compliance with high dexterity to access the
surgical target sites along tortuous anatomical paths under constrained environments and …

We present a prototype of a flexible nitinol needle (φ 1.0 mm and length 172 mm) integrated
with an array of 12 Fiber Bragg Grating (FBG) sensors. These sensors measure the axial …

Needle insertion procedures are commonly used for surgical interventions. In this paper, we
develop a three-dimensional (3D) closed-loop control algorithm to robotically steer flexible …

Fiber-reinforced plastic (FRP) composites are utilized extensively in various high-end
industries. Therefore, developing a proper sensing and monitoring system is crucial to …

A new type of fiber optic sensor has been developed for sensing relative humidity (RH). This
RH sensor was fabricated by using a hetero-core optical fiber structure that was coated with …

This book presents the basic principles of optical sensor technology in line with the
tremendous development in the concept of optical fibers. In the first four chapters, the book …

This paper presents a method for measuring two components of bending force and
temperature using one sensor head. Indirect inference based on the spectra of two fiber …

The 3D shape sensing of flexible morphing wing using fiber Bragg grating (FBG) sensors is
presented in this paper. A morphing wing prototype with polyimide thin film skin is …

Soft actuators are the components responsible for organs and tissues adsorptive fixation in
some surgical operations, but the lack of shape sensing and monitoring of a soft actuator …

A space curved surface shape reconstruction algorithm is proposed for shape perception
and reconstruction of flexible plate structure. First, biorthogonal strain data measured by …
