We propose a new type of fiber hydrophone composed of an etched fiber Bragg grating and a special packaging structure for detecting acoustic waves in the low-frequency band under water. The operating mechanism is based on the mechanical vibration of

A novel fiber anemometer based on two pairs of fiber gratings is experimentally demonstrated and can simultaneously detect wind speed and wind direction. One pair of gratings, which are separated by 90° in space, is fixed on a small stainless steel

We present a novel two-dimensional fiber-optic inclinometer with high sensitivity by crisscrossing two etched chirped fiber Bragg gratings (CFBG) arrays. Each array is composed of two symmetrically-arranged CFBGs. By etching away most of the cladding

We successfully achieved surface modification of Si at a low temperature (150 °C) by using citric acid and ascorbic acid as surface modifiers and enhanced the electrochemical performance of a Si-based anode. A simple planetary ball-milling process f

We demonstrate a novel fiber-optic hydrophone by using a fiber Bragg grating as a sensing element for underwater acoustic wave detection. The effects of fiber diameter, fiber tension, film thickness, and film radii are investigated for optimal perfor
