Moisture-electric energy transformation (MEET) technology is being developed to further expand the utilization of environmental energy sources like thermal power, wind power, hydropower, and solar energy. The goal of the MEET technology is to extract power from environmental moisture with as few conversion processes as possible to satisfy the ever-growing demand for new and more portable energy sources The use of cold spray to produce MEET devices results in a greener process. While the suitability of polyether ether ketone as a MEET material was proven and the deposition of PEEK using cold gas dynamic spray (CGDS) was achieved, additional work is needed to fully characterize the manufacturing of PEEK-based MEET devices via CGDS.
