Low-voltage, ultra-broadband wearable MEMS ultrasound: a frequency-merged, wafer-scale framework for continuous in vivo cardiovascular imaging and monitoring

Continuous, non-invasive monitoring of central hemodynamics is essential for advanced cardiovascular care. Although wearable ultrasound enables deep-tissue sensing, its widespread clinical adoption is limited by the inherent physical trade-off between driving voltage and acoustic bandwidth, alongside the challenges of...
