Without any delays, here are the best Phones with Ultrasonic Fingerprint Sensors (June 2025) that make the cut: ...

Abstract: Transient ultrasonic waves in a fluid medium generated ... Here, DPSM is extended to the time domain without the fast Fourier transform (FFT) but using the Green's function in the time ...

Here, however, we show that the use of fast Fourier transform electrochemical impedance spectroscopy (FFT-EIS) to interrogate EAB sensors leads to improved (here better than 2 s) time resolution and ...
