What's Happening?
Researchers at the University of California, Berkeley, have developed a new implantable ultrasound-based system for continuous blood pressure monitoring. This device, detailed in a study published in Microsystems
& Nanoengineering, uses a subcutaneous array of piezoelectric micromachined ultrasonic transducers (PMUTs) to measure arterial diameter changes and reconstruct blood pressure waveforms. The system has been tested in vitro and in vivo, including implantation in a sheep, showing clinically acceptable error margins. This innovation aims to provide a more comfortable and accurate alternative to traditional blood pressure cuffs and wearable sensors, which often suffer from discomfort and alignment issues.
Why It's Important?
This development is crucial for the management of hypertension, a leading cause of cardiovascular diseases. Traditional blood pressure monitoring methods are often intrusive and unsuitable for continuous use, whereas this new device offers a minimally invasive solution that can provide real-time data without disrupting daily activities. The ability to continuously monitor blood pressure with high accuracy could significantly improve patient outcomes by enabling early detection and management of hypertension. This technology also holds potential for integration into digital health platforms, offering a comprehensive approach to cardiovascular health management.
