Abstract

In this work, a flexible transparent CMUT array is fabricated for through-illumination photoacoustic applications in which shape conformality is required. The array is composed of glass pieces with transparent structural layers on them, which are connected to each other via PDMS, making the array flexible. Unlike the previous flexible devices in the literature, the array is very robust to bending. The photoacoustic image of a wire target was successfully reconstructed using the fabricated flexible transparent CMUT array. The fabricated device offers promise for future photoacoustic tomography systems with through-array illumination.
