title: Development of an arterial tonometer sensor.
abstract: In this study, we developed arterial tonometer sensor array using piezoresistive sensor elements and PDMS coating. Computer simulation for the pressure response of the sensor was compared with measurement results. The pressure attenuation ratios for simulation and measurement by 3mm PDMS coating were 0.2145 and 0.2952, respectively. It is expected that sensitivity of the sensor array depending on PDMS coating thickness can be determined using proposed method. And by designing the sensor bonding layer and wire bonding layer separately, it can improve wire connection reliability.
