Conventional POCUS systems are based on piezoelectric transducers and cable-connected electronics, which require a costly manufacturing process and usually come with an undesirably limited channel count. Such devices typically serve a specific subset of clinical applications, as imaging at different body parts calls for different ultrasound frequencies that are beyond the bandwidth of a single piezoelectric transducer. To enable whole-body imaging, multiple probes with different
