Photograph of the ultrasonic link (a) without and (b) with sound-attenuation medium (porcine tissue). Dependence of the output voltage and the output power on the load resistor (c) through oil and (d) through sound-attenuation medium. Input signals to ultrasound transducer and the output signal from the μTUD driven by (e) 20-cyc and (f) 40-cyc sine waves (1 MHz, ~85 mm separation in oil).
