Beam steering and control of large area ultrasound actuator arrays for haptic perception KU Leuven
Traditional microphone units focus on human perceptible sound waves (between 20 Hz and 20 kHz). Acoustic development also focuses on ultrasound, compromising the frequencies above the detection limit of the human ear (from 20 kHz to several GHz). These sound waves can be used for a wide variety of applications, including medical imaging, therapeutic treatment, non-destructive testing and position localization of objects. Nowadays, ultrasonic ...
