RESUMEN
OBJECTIVE: This study proposes a novel wearable pulse monitoring system, which can realize the synchronous measurements of pulse wave, skin, temperature, and pulse wave velocity (PWV). METHODS: A flexible sensor based on thermosensation is used to detect pressure and temperature stimuli simultaneously. A total of two sensors are integrated to detect pulse transit along two specific points of the artery, e.g., Cun and Chi at a wrist, the data of which are subsequently used to figure out the PWV by using a tailor-designed algorithm conducted in a microprocessor. Calibration experiments and application cases are conducted to validate the effectiveness of the monitor. RESULTS: The developed monitor detects the physiological signals of pulse wave, PWV, and skin temperature simultaneously. In addition, the monitor can measure the pulse changes before and after exercises and track skin temperature variations when warming and cooling. Moreover, the monitor can be also used to detect the local PWV at the wrist. CONCLUSION: The synchronous measurements of pulse wave, skin temperature, and PWV using a wearable monitor are feasible. SIGNIFICANCE: The monitor is small, simple-structured, with multifunction, and thus provides a promising auxiliary approach for traditional Chinese medicine pulse diagnosis.

It has been suggested that arterial stiffness is one of the most important risk factors for the development of a cardiac infarction or stroke. As cardiovascular disease remains the number one killer of individuals before the age of 75, the early detection of cardiovascular disease and its prevention remains paramount in order to sustain a healthy longevity. This article looks at the latest noninvasive technology that can measure arterial stiffness quickly and easily and also highlights a small open trial in which supplements were used to determine their efficacy in helping to reverse/improve arterial stiffness.
