A new blood pressure patch called BioBeat is revolutionizing how doctors monitor blood pressure. The patch integrates sensors for blood pressure, glucose, lactate, alcohol, and caffeine, offering a comprehensive health monitoring solution.
Furthermore, the patch’s design includes a blood pressure sensor with ultrasound transducers for precise readings and chemical sensors for detecting biomarkers in sweat and interstitial fluid. The study conducted tests where subjects wore the patch while performing various activities like exercising, consuming high-sugar meals, alcohol, and caffeine. Results showed close alignment with commercial monitoring devices such as blood pressure cuffs and glucometers.
The research team behind the patch are the scientists of the University of Miami, USA. They faced challenges in eliminating signal interference between sensors, leading to innovative solutions like optimal sensor spacing and using solid ultrasound gel to prevent leakage.
Dr. Maria Delgado, a hypertension specialist at the University of Miami Comprehensive Hypertension Center, highlighted the importance of accurate blood pressure readings due to the prevalence of hypertension. Traditional cuff measurements may not always reflect true values, especially in cases of “white coat syndrome.” The BioBeat patch allows continuous monitoring, even during sleep, providing a more comprehensive understanding of blood pressure trends. Additionally, UC San Diego researchers are developing a smaller ultrasound patch for tracking blood pressure using soundwaves. This innovation offers a promising alternative to conventional cuff measurements, enhancing patient care and monitoring capabilities.
Future iterations of the patch aim to incorporate more sensors for monitoring additional biomarkers associated with various diseases, enhancing its clinical value and making it a fully wearable, wireless system.
