Capacitive micromachined ultrasonic transducers (CMUTs) have a nonlinear relationship between the applied voltage and the emitted signal, which is detrimental to conventional contrast enhanced ultrasound (CEUS) techniques. Instead, a three-pulse ampl

Oral drug delivery is a preferred method for drug administration because it is economical and convenient to the patient [1]. Uptake from the gut to the blood is mediated by the intestinal barrier, which exhibits some selectivity, i.e., mechanisms in
