Track Code: 2016-097 Short Description     An approach for measuring ambulatory blood pressure using a two-dimensional force sensor array and photoplethymogram.  #cardiology #medicaldevice #diagnosticsandmeasurements #mems #actuator  Abstract         Hypertension affects over 29% of adults in the United States and accounts for an estimated 12.8% of all deaths worldwide. The chronic condition is a significant risk factor for cardiovascular disease and increases risk of heart attack, stroke, kidney problems, and death. The leading device to measure blood pressure is the traditional cuff which has limited sensitivity and specificity. Blood pressure readings are often inaccurate due to the device’s intermittent use and confinement to office settings. Healthcare professionals increasingly seek continuous 24-hour monitoring, called ambulatory (AMBP) monitoring, to detect and manage hypertension.  Even though AMBP monitoring has increased accuracy and demonstrated potential to improve patient outcomes, current options are bulky and expensive.  Northwestern researchers are solving this problem with a flexible wristband design. The device integrates data from a pressure-sensor array and a pulse oximeter to achieve the best readings possible. Continuously worn, the device measures ambulatory blood pressure noninvasively and may be integrated into smart watches for user convenience.
