A Row-Column (RC) Addressed 2-D Capacitive Micromachined Ultrasonic Transducer (CMUT) Array on a Glass Substrate
Sanders, J. L., Biliroglu, A. O., Wu, X., Adelegan, O. J., Yamaner, F. Y., & Oralkan, O. (2021, March). IEEE TRANSACTIONS ON ULTRASONICS FERROELECTRICS AND FREQUENCY CONTROL, Vol. 68, pp. 767–776.
author keywords: Electrodes; Substrates; Imaging; Impedance measurement; Two dimensional displays; Glass; Acoustics; Capacitive micromachined ultrasonic transducer (CMUT); glass substrate; row-column (RC) array; ultrasound imaging
TL;DR:
A row-column capacitive micromachined ultrasonic transducer array fabricated using anodic bonding on a borosilicate glass substrate is presented to reduce the bottom electrode-to-substrate capacitive coupling and improves the relative response of the elements when top or bottom electrodes are used as the “signal” (active) electrode.

2017 conference paper
Multi-wavelength photoacoustic imaging for monitoring lesion formation during high-intensity focused ultrasound therapy
Photons plus ultrasound: imaging and sensing 2017, 10064.
TL;DR:
A machine-learning-based method for lesion monitoring with multi-wavelength PAI (MWPAI), where PAI is repeated at a sequence of wavelengths and a stack of multi-Wavelength photoacoustic images is acquired, which shows that the lesions can be identified clearly.
