Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

ANS(autonomic nervous system) Watch has been developed as to detect pulse waves using a pressure detector. It is used to measured cardiovascular indices, including cardiac output, and vessel stiffness. ANSWatch is developed to apply to the prediction of traditional Chinese medicine (TCM) pulses, such as the wiry pulse. There are 28 types of pulses in TCM. Among them, the slippery pulse is the most commonly seen pulse in pregnant women. The present project plans to detect pregnant pulses using this portable ANSWatch connected to a laptop. One hundred pregnant women and 100 non-pregnant women will be recruited. After taking the indices of the subjects, a neural network is designed to provide the prediction for pregnancy constitution, pregnancy pulse and slippery pulse in pregnant women.
