Abstract: An imaging sensor package includes: an imaging sensor; and an architected substrate coupled to a bottom surface of the imaging sensor. The architected substrate has local stiffness variations along an in-plane direction of the architected substrate, and the imaging sensor and the architected substrate are curved.

Abstract: Some variations provide a pre-ceramic matrix composite comprising: a precursor pre-ceramic matrix; reinforcing elements disposed within the precursor pre-ceramic matrix; and a compressible material disposed on the surface of the reinforcing elements and interposed between the reinforcing elements and the precursor pre-ceramic matrix. Other variations provide a ceramic matrix composite comprising: a ceramic matrix; reinforcing elements disposed within the ceramic matrix; and a compressed material disposed on the surface of the reinforcing elements and interposed between the reinforcing elements and the matrix. The coating of compressible material prevents cracking during processing because the coating absorbs stresses associated with volumetric shrinkage of the ceramic matrix during densification, thereby reducing the stresses at the interface between the reinforcing elements and the ceramic matrix. Methods of fabricating ceramic matrix composites using the principles of the invention are disclosed.
