摘要：
In this paper, we present a new design and development of embedded chirped fiber grating for sensing local pressure in the range 0-30 N along the length of the grating. The sensor can also detect the location of the force. The embedding design is supported with experimental results, which show that the change in reflected intensity varies linearly with the applied pressure. The reflected wavelength where the change is observed varies linearly with the point of application of the force. (C) 2002 Elsevier Science B.V. All rights reserved.
