陶瓷的加工是各种技术应用的重要技术。本文介绍了一种由喷涂和激光结构组成的高度可控的工艺，用于在通用基板上设计陶瓷层。热电氧化物Ca3Co4O9是一种热电材料，用于该工艺并应用于柔性陶瓷衬底。所得到的结构具有高度可控的形状和良好的热电性能，它们可用于生产可打印热电发电机（TEG）。柔性陶瓷衬底的使用和该工艺的高可行性导致了一种普遍适用的程序，可用于加工具有独特结构和设计的陶瓷。
The processing of ceramics is an important technology for various technical applications. In this paper, a highly controllable process consisting of spray-coating and laser structuring to design ceramic layers on a versatile applicable substrate is presented. A thermoelectric oxide, Ca3Co4O9, which is a type of thermoelectric material, is used in the process and applied to a flexible ceramic substrate. The resulting structures have highly controllable shapes and good thermoelectric properties, and they can be used to produce a printable thermoelectric generator (TEG). The use of a flexible ceramic substrate and the high feasibility of the process lead to a universally applicable procedure that can be used to process ceramics with unique structures and designs.
