Abstract
A photostructurable ceramic is processed using photostructuring process steps for embedding devices within a photostructurable ceramic volume, the devices may include one or more of chemical, mechanical, electronic, electromagnetic, optical, and acoustic devices, all made in part by creating device material within the ceramic or by disposing a device material through surface ports of the ceramic volume, with the devices being interconnected using internal connections and surface interfaces.
Claims16
An embedded acoustic device, comprising:
- a photostructurable ceramic volume encapsulating plumbing, the plumbing comprising:
- at least one cavity;
- at least one conduit providing a fluidic path between the at least one cavity and an outer surface of the photostructurable ceramic volume;
- a fluidic device material disposed in the at least one cavity, the fluidic device material being an acoustic material that forms an acoustic device encapsulated by the ceramic volume.

An embedded acoustic device, comprising:
- a photostructurable ceramic volume encapsulating plumbing, the plumbing comprising:
- at least one cavity;
- at least one conduit providing a fluidic path between the at least one cavity and an outer surface of the photostructurable ceramic volume;
- a fluidic device material disposed in the plumbing and forming an acoustic device;
- and
- the acoustic device comprising an acoustic guide, the acoustic guide including at least one sound-driver conduit, each sound-driver conduit extending from the outer surface to the at least one cavity to provide an acoustic path between the outer surface and the at least one cavity, wherein the sound driver conduit comprises an acoustic material;
- the ceramic volume comprising surface interface for coupling an acoustic wave with the fluidic device material through the sound driver conduit.
