Low-cost and miniature all-silica Fabry–Perot pressure sensor fo...

The monitoring of increased intracranial pressure (ICP) is necessary in the diagnosis and treatment of patients with neurological disease because it can provide an insight into the mechanism of the head injury. In this letter, we develop a novel miniature Fabry–Perot (F-P) sensor for ICP measurement. The proposed sensor is fabricated by using a commercially available fusion splicer and a fiber cleaver, by which many difficult art problems involved in fabrication are solved and the online monitor
