[Design of an implantable sensor for detecting uterine musculature deformation and analysis of its performance].

In gynecology, it is very important to obtain the parameters of women's uterine musculature, such as its deformation size and contraction frequency, etc. This paper proposes a type of sensor for measuring these parameters and also analyzes its force situation. The sensor is flexible, deformable, and can adjust itself to the shape of the uterus. It can be put into the women's uterine cavity easily. The experiment shows that the sensitivity of the left and right sets coils of the sample sensor achieves 22.38 nH/mm2, while that of the top set coils achieves 22.84 nH/mm2, and the reaction time of the sensor is less than 200 ms. These results can meet the requirements of sensitivity and reaction time for testing the contraction situation of uterine musculature. The sensor has been applied in some medical fields.
