Non-invasive cardiac sensing via an acoustic Helmholtz resonator cavity with electrocardiogram waveform reconstruction

Physiological markers are a primary source of prognostic health monitoring systems. Specifically, with heartbeat sensing, many ailments may be identified in their nascent stage. In clinical settings, the human heartbeat is measured by way of an electrocardiogram (ECG). Common met...

Scattering-free subwavelength acoustic direction sensing via virtual acoustic resonance

Conventional direction sensing relies on digital phase extraction after analog-to-digital conversion, which becomes computationally demanding as subwavelength phase differences shrink. Here, we introduce a virtual resonance approach that performs phase-to-amplitude transduction i...
