    "abstract": "Arterial Blood Pressure wave monitoring is considered to be important in\nassessment of cardiovascular system. We developed a novel pulse wave detection\nsystem using low frequency specific piezoelectric material as pressure wave\nsensor. The transducer detects the periodic change in the arterial wall\ndiameter produced by pressure wave and the amplified signal after integration\nrepresents the pressure wave. The signal before integration is proportional to\nthe rate of change of pressure wave and it not only reproduces the pressure\nwaveform faithfully, but also its sharper nature helps to reliably detect the\nheart period variability (HPV). We have studied the position-specific (e.g.\nover carotid or radial artery) nature of change of this pulse wave signal\n(shape and amplitude) and also the changes at different physiological states.",
