Abstract

Monitoring local brain temperature with high spatial precision is essential to understanding neurophysiological processes and managing the side effects of optical neuromodulation techniques. We present a novel multifunctional neural interface integrating a microscale resistance temperature detector (µRTD) onto the curved surface of a tapered optical fiber (TF), enabling co-localized light delivery and thermal sensing with minimal footprint. The µRTD, patterned via an unconventional two-photon polymerization (TPP)-based process on the fiber surface, exhibits thermal sensitivity
