Multi-layer sensors are made using a direct write deposition technology. The sensors are formed on the surface of an object having a system characteristic to be monitored, such as temperature and strain. A first layer is deposited onto the substrate of the object to be monitored, a second layer is deposited onto the first layer, and a third layer is deposited onto the second layer. An optional protective layer may be deposited between the first layer and the substrate to prevent chemical interaction and lack of adhesion therebetween.

The invention relates to a novel ceramic tableware repairing technique, comprising the following repairing steps: (1) cleaning and cohering; and (2) repairing breakage, wherein the method for repairing breakage has three situations as follows: 1) if the rim or the ventral and bottom part of the tableware is incomplete, the incomplete part can be repaired by carrying out rollover and sampling on the originally preserved block through mould paste; 2) the incomplete part can not be subjected to rollover on the original tableware, so a mould can be manufactured by only taking the modeling characteristic of similar tableware as a reference, and then rollover repairing is carried out; and 3) as for the tableware of which most parts are incomplete, the first step is to find fragments which are made of similar materials and have same shapes with the incomplete parts to match with the incomplete parts of the tablewares, and then repairing is carried out; and coloring and glazing can be finished by one step if the glaze layer is thin, and coloring and glazing need to be performed independently if the glaze layer is thick or the glaze layer with a glass texture is expected. By the invention, no obvious difference exists between new tableware and repaired tableware and can not be distinguished by naked eyes.
