In learning and evaluation of acupuncture manipulations

there are lack of quantitative physical parameters on exertion strength

duration and direction of acupuncture technique at present. Based on the tactile parameters collected during "twirling" and "lifting-thrusting" of needling

a kind of array polyvinylidene fluoride(PVDF) tactile sensor was designed. Followed by

a window segmentation method for tactile signal was proposed and the time domain features of the window were extracted. Finally

an identification method of acupuncture manipulation based on FCM(Fuzzy C-Means) was constructed. Through the experiment

it was proved that this sensor can effectively identify the four kinds of basic acupuncture manipulations

i.e. reinforcing by twirling and rotating

reducing by twirling and rotating

reinforcing by lifting and thrusting and reducing by lifting and thrusting and it was conductive to the quantification and dissemination of acupuncture manipulations.
