| Abstract Scope |
Global concerns regarding energy and the environment have created an urgent demand for sustainable manufacturing, usage, and disposal of electronic components. Piezoelectric ceramics are extensively used due to the rapid development of the Internet of Things (IoT) and green energy production, which require large quantities of piezoelectric sensors and energy harvesters as functional components and power sources, respectively. Piezoelectric ceramics either contain hazardous elements or need a large energy budget for manufacturing and thus, their recycling needs to be carefully considered. This work develops upside-down composites to recycle waste oxide perovskite-based piezoelectric ceramics. Production of the recycled and reusable materials requires only a marginal energy budget whilst achieving a high level of material densification and excellent sensing capabilities. The work also develops the recycled materials towards machine learning-driven routes that are compatible with high-throughput manufacturing. |
