A method of forming a piezoelectric device may include depositing a sol-gel film over a substrate and curing the sol-gel film by impinging light onto an exposed surface of the sol-gel film to form a piezoelectric ceramic element. The method may produce a piezoelectric composite material including at least two piezoelectric ceramic pillars over the substrate. The at least two piezoelectric pillars may include at least one layer. The at least one layer having a gradient density, such that a first portion of the at least one layer proximate the substrate has a density lower than a second portion that is located a greater distance from the substrate than the first portion. The piezoelectric composite material may further include a resin separating the at least two piezoelectric ceramic pillars.

An apparatus and method of embedding an optical fiber within a substrate. The apparatus includes a bonding device and a conveyance device. The bonding device bonds a foil layer to the substrate to seal the optical fiber within a groove of the substrate. The conveyance device moves the substrate and the bonding device relative to each other. Relative motion between the substrate and the bonding device draws the optical fiber into the groove and the foil layer over the optical fiber at a collection point.
