Development of viscoelasitic property sensor for micro-stirrer using fiber blagg grating

The intracerebral hematoma might cause the critical decease if the hematoma could not be dissolved within several hours after it was formed. Effective stir to dissolve the hematoma will change by the condition around tip of micro-stirrer. This paper presents a fundamental experiment to measure the viscoelastic property of hematoma using micro-stirrer with fiber blagg grating. The viscoelastic property feature of imitated hematoma can be calculated and the performance of measurement was verified experimentally.
