Abstract
A miniature all-fiber in-line tip pressure sensor fabricated by 157nm laser pulses is proposed and demonstrated, for the first time to our knowledge. Such a pressure sensor can be operated under high temperature due to its all silica structure. The sensor has been tested for pressure sensing over 0MPa~60MPa, showing a pressure sensitivity of ~83.3pm/MPa, an excellent linearity of 99.998%, and a long-term stability of ±0.03MPa, respectively. Such a miniature fiber-optic pressure sensor could find important applications in automotive and aerospace industries, and down-hole monitoring, etc, due to its extreme compactness, capability for operation at high temperature, easy fabrication, excellent stability, good potential for mass-production.
