In Vivo Evaluation of Thermally Drawn Biodegradable Optical Fibers as Brain Implants

Journal of Biomedical Materials Research Part B: Applied Biomaterials, Volume 113, Issue 3, March 2025.
ABSTRACT Optical fiber technology plays a critical role in modern neuroscience towards understanding the complex neuronal dynamics within the nervous system. In this study, we manufactured and characterized amorphous thermally drawn poly D, L‐lactic acid (PDLLA) biodegradable optical fibers in different diameters.

Tapered Fiber Coated with Hydroxyethyl Cellulose/Polyvinylidene Fluoride Composite for Relative Humidity Sensor

Advances in Materials Science and Engineering, 2013
A simple relative humidity (RH) sensor is demonstrated using a tapered fiber coated with hydroxyethyl cellulose/polyvinylidene fluoride (HEC/PVDF) composite as a probe. This coating acts as an inner cladding whose refractive index decreases with the rise
