MEMS Optical Scanner made from Microscopic Graphite Fibers and Method of Fabrication
We report the development of novel carbon fiber-integrated MEMS (FIM)structures which can achieve extremely large deformations at high speedswith nearly fatigue-free behavior. FIM cantilevers fabricated using single 5 µmdiameter carbon fibers demonstrated tip deflections exceeding 90° atfrequencies of 8–30 kHz, and sustained these deflections for over 1010cycles. Using existing MEMS fabricationtechniques, carbon fiber-based MEMS optical scanners were subsequentlyfabricated with demonstrated angular scans >160° at a 2.5 kHz resonance.
