title: An ultrawideband radar based pulse sensor for arterial stiffness measurement.
abstract: A novel pulse sensor based on ultrawideband (UWB) radar to detect the arterial vessel movements on various sites on human body without applying external pressure on the arterial vessel was designed and evaluated for aortic stiffness measurement. The UWB pulse sensor was evaluated for its functional performance and human study was carried out to validate the UWB sensor as a tool for clinical screening of subjects with cardiovascular risks. Good agreement in measurement of pulse wave velocity, an index of arterial distensibility, was achieved between the UWB pulse sensor and the applanation tonometer.
