摘要： Methods and systems of fabrication of high resolution, high-throughput electrochemical sensing circuits on a substrate. High resolution electrochemical sensing circuits are printed by an effective additive technique to the substrate. Optionally, post-print annealing converts electrochemically inactive printed graphene into one that is electrochemically active. The printing can be by aerosol jet printing, but is not necessarily limited thereto. An example is inkjet printing and then the post-print annealing. Ink formulation would be adjusted for effectiveness with inkjet printing. Optionally biorecognition agents can be covalently bonded to the printed graphene for the purpose of electrochemical biosensing. High throughput fabrication of high-resolution graphene circuits (feature sizes in the tens of microns

摘要： There is described, in accordance with a first aspect of the invention, a laser treatment system and method for, in particular, imparting beneficial residual stresses into a desired part (P) during production thereof by a Selective Laser Sintering or Melting (SLS/SLM) process, the method including the step of repeatedly subjecting the desired part (P) to an in-situ Laser Shock Peening (LSP) treatment as the desired part (P) is gradually being produced during the SLS/SLM process. The in-situ LSP treatment includes selectively bringing an LSP module (20) in contact with a surface (S) of the desired part (P) being produced during the SLS/SLM process and subjecting the LSP module (20) to the action of a first laser beam (LLSP) to impart beneficial residual stresses into the desired part (P). According to this first aspect of the invention, the LSP module (20) is movable between a building chamber (30) where the desired part (P) is being produced, for the purpose of carrying out the in-situ LSP treatment, and a separate storage chamber (35) located adjacent to the building chamber (30), when the LSP module (20) is not used for the purpose of carrying out the in-situ LSP treatment. This first aspect of the invention is implementable in a corresponding additive manufacturing system and method. Further aspects of the invention are described.
