Abstract
Acoustic sensors with one or more microlens structures, as well as methods for fabricating and operating such acoustic sensor systems are disclosed. In some embodiments, an apparatus may include: an acoustic sensing element; a display stack; a first layer of material having a first acoustic refractive index and one or more microlens structures disposed at a first surface of the first layer of material; and a second layer of material disposed on the first layer of material and the one or more microlens structures, the second layer of material having a second acoustic refractive index that is different from the first acoustic refractive index. The one or more microlens structures may be configured to form a focused pressure wave from one or more acoustic signals emitted by the acoustic sensing element.
