Abstract: Apparatuses, systems, and methods for electrical field-assisted heterogeneous material printing (EF-HMP) of metal-polymer composite structure include a printing platform, a solution tank, an optical projection system, and an electrical field generation and control module. An additive manufacturing method for a metal-polymer composite structure includes preparing a photocurable electrolyte solution by mixing a photocurable liquid resin with a conductive nanofiller, a metal salt solution, a photo initiator, and deionized water. The method further includes initiating photopolymerization of the photocurable liquid resin to form a photocured polymer matrix by directing a projection of ultraviolet light energy from a light source onto the photocurable electrolyte solution. The method further includes depositing a metal structure onto the photocured polymer matrix. In this manner, both the photopolymerization and the metal electrodeposition are performed using the same photocurable electrolyte solution.

Abstract: This disclosure provides a monitoring device, a wireless communication device, and a control method. The monitoring device includes a control system assembly, a digital-analog mixing assembly, a frequency band selection assembly, and an antenna. The control system assembly is respectively connected with the digital-analog mixing assembly and the frequency band selection assembly; one end of the frequency band selection assembly is connected with the digital-analog mixing assembly through a channel of designated frequency band, and the other end of the frequency band selection assembly is connected with the antenna. The monitoring device can switch from a currently used frequency band to other frequency bands for signal transmission or use other frequency bands for simultaneous signal transmission, according to a signal transmission status of the currently used frequency band. Thus, the anti-interference ability of the monitoring device can be improved to reduce the error rate of signal transmission.
