Article Synopsis
- Continuous blood pressure (BP) monitoring is essential for reducing global mortality from hypertension, relying heavily on the accuracy of pressure sensors used in BP devices.
- A flexible resistive pressure sensor made from reduced graphene oxide and a polydimethylsiloxane sponge was developed, demonstrating high sensitivity and significant changes in resistance with pressure, ideal for effective BP monitoring.
- The sensor successfully measured systolic and diastolic BP, conforming to established protocols and showing minimal error when compared to traditional BP monitors, thereby validating its potential for medical applications.
In recent times, the high demand for flexible and wearable pressure sensors to monitor human health, particularly for patients afflicted with hypertension or high blood pressure (BP), has captured the keen interest of researchers. Capacitance-based flexible sensing devices offer real-time metrics regarding vital physiological parameters of the human body, such as BP and pulse rate (PR), thereby enabling the identification of cardiovascular complications. In this regard, we have developed a capacitive pressure sensor using polydimethylsiloxane (PDMS) and deionized water (DIW) and improved its key parameters by adding baking powder to PDMS-DIW.

The porosity/flexibility of PDMS has been increased by altering its microstructure by incorporating a thin layer of a scrubber into the dielectric layer to improve the pressure sensitivity. The fabricated sensor with a porous PDMS-scrubber composite (microstructured/porous PDMS layer) shows 0.
