摘要：
A pulse sensing module used in a blood pressure measuring device attached to the skin to allow at least one of systolic pressure Psystolic, diastolic pressure Pdiastolic, and blood pressure variation to be measured according to an embodiment of the present disclosure includes a piezoelectric layer that includes a piezoelectric material for generating a piezoelectric effect due to a pulse and a protective layer that is applied to the piezoelectric layer to protect the piezoelectric layer, allows a poling process of applying a high voltage to the first electrode line and the second electrode line formed on the piezoelectric layer to improve the polarity of the piezoelectric material, and has an opening for allowing a portion of the first electrode line and a portion of the second electrode line to be exposed.
