patch are promising for next-generation health monitoring. They have the potential to enable impactful applications such as blood-pressure, cardiac, bladder, and respiratory monitoring. Research in this area to date has focused on the realization of patch-based flexible ultrasound transducers, while the significant challenges associated with the required battery-powered miniaturized electronics have remained largely unaddressed. A key challenge is the efficient driving of the US transducer from a battery (Fig. 6.4.1). To generate sufficient acoustic pressure, excitation voltages of 10’s of volts are required. In conventional US devices, the transducer is driven by a simple and compact class-D pulser. However, this is associated with CV2 losses due to the charging and discharging
