In order to quantify the manipulation process of acupuncture, in this
article, a piezoelectric glove based wearable stress sensing system is
presented. Served as the sensitive element with small volume and high
tensile resistance, PVDF greatly meet the need of quantitative analysis.
Through piezoelectric force sensing glove, the system is capable of
detecting both perpendicular stress as well as shear stress. Besides,
key parameters including peak stress at needle are detected and
extracted, potentially allowing for a higher learning efficiency hence
advancing the development of acupuncture.
