Abstract

This seminar consists of two parts: two fibre optical needle-tip sensing techniques for medical applications and two stretchable sensing techniques for soft robotic applications.

 First, I will presenttwo novel fibre optics based needle-tip sensing techniques for in vivo biopsy and minimally invasive spinal surgeries (MISS). The first sensor uses the Fabry-Perot Interference (FPI) for the needle-tip tactile sensing and identification of type of tissues. The optical circuit, signal processing and temperature compensation are discussed, and the experimental setup and results with phantom and bovine tissues are presented. The second sensor uses Raman spectroscopy for in vivo nerve detection. The sensing principle and the design of miniaturised Raman probe are discussed, the algorithm for classification of Raman signatures is given, and preliminary experimental results are presented.

Second, I will present two stretchable sensors for soft-bodied robotic applications, (1) Nanocomposite-Based Stretchable Deformation Sensor and (2) Stretchable Multimodal Senor for Strain, Pressure and Shear Stress, including their design, fabrication, characterization and applications.
