Abstract

In the application of micro-structural monitoring, one kind of flexible and stretchable sensing elements was urgently demanded to detect the micro-bending and surface distortions, such as micro-bend sensing elements of medical catheter or smart skin sensing unit of micro-robots. Here the sensing element must be stretchable and flexible for free operation, and must be safe enough when used in bio-medical situation. Although the optical fiber grating is very mature and can be used as sensing element in micro-bending situation, it isn't stretchable enough and flexible enough when used in bio-medical science and micro- structural monitoring, and when applied in human body, the fiber grating isn't safe enough for its easily broken character. In this paper a kind of novel flexible and stretchable polymer grating sensing elements was fabricated by micro-replication process which could be used in micro- structural monitoring, and detailed processes was presented and discussed.
