Micro-electro-mechanical devices\u00a0(MEMS)\u00a0are based on the\u00a0integration of mechanical and electrical components on a micrometer scale. We all use it continuously in our everyday life: for example\u00a0in our mobile phone there are at least a dozen MEMS\u00a0that regulate different activities ranging from motion, position and inclination monitoring of the phone, active filters for the different transmission bands and the microphone itself.<\/p>\n\n\n\n
Even more interesting is\u00a0the extreme nanoscale miniaturization of these devices (NEMS), because it offers the possibility of creating inertial, mass and force sensors with such sensitivity that they\u00a0can interact with single molecules, writes Politecnico di Torino in a press release<\/a>.<\/p>\n\n\n\n However, the diffusion of NEMS sensors is still limited by the high manufacturing cost of traditional silicon-based technologies. Conversely,\u00a0new technologies such as 3D printing have shown that similar structures can be created at low cost and with interesting intrinsic functionalities, but to date the performance as mass sensors are poor.<\/p>\n\n\n\n The article\u00a0“Reaching silicon-based NEMS performances with 3D printer nanomechanical resonators”\u00a0published in the prestigious journal\u00a0Nature Communications\u00a0shows how\u00a0it is possible to obtain mechanical nanoresonators from 3D printing\u00a0with figures of merit such as quality factor, published stability, mass sensitivity and strength comparable to those of silicon resonators. The research is the result of the collaboration between the\u00a0Politecnico di Torino\u00a0\u2013 thanks to the research activity of\u00a0Stefano Stassi\u00a0and\u00a0Carlo Ricciardi\u00a0from the\u00a0Department of Applied Science and Technology-DISAT\u00a0together with\u00a0Mauro Tortello\u00a0and\u00a0Fabrizio Pirri\u00a0(NAMES\u00a0and\u00a0MPNMT\u00a0groups) – and the\u00a0Hebrew University of Jerusalem, with the research of\u00a0Ido Cooperstein\u00a0and\u00a0Shlomo Magdassi.<\/p>\n\n\n\n The different nanodevices (membranes, cantilever, bridges) were obtained by\u00a0two-photon polymerization\u00a0on new liquid compositions, followed by a\u00a0thermal process that removes the organic content, leaving a\u00a0ceramic structure\u00a0with high rigidity and\u00a0low internal dissipation. The samples thus obtained are then characterized by\u00a0Laser Doppler vibrometry.<\/p>\n\n\n\n \u201cThe NEMS that we have fabricated and characterized – explains\u00a0Stefano Stassi\u00a0\u2013 have mechanical performances in line with current silicon devices, but they are obtained through a simpler, faster and more versatile process, thanks to which it is also possible to add new chemical-physical functionalities. For example, the material used in the article is Nd: YAG, normally used as a solid-state laser source in the infrared range”<\/p>\n\n\n\n \u201cThe ability to fabricate complex and miniature devices that have performance similar to silicon ones\u00a0\u2013 says\u00a0Shlomo Magdassi\u00a0–\u00a0by a quick and simple 3D printing process, brings new horizons to the field of additive manufacturing and rapid manufacturing.\u201d<\/p>\n\n\n\n The work was developed within the research projects PRIN 2017- Prot.20172TZHYX, funded by the Ministero dell\u2019Universit\u00e0 e della Ricerca (MUR) and H2020 FET Open \u201cBoheme\u201d, funded by the European Union, and by Israel Ministry of Science and Technology and the National Research Foundation, Prime Minister\u2019s Office, Singapore, under its Campus of Research Excellence and Technological Enterprise (CREATE) program.A simpler process to create sensors<\/h3>\n\n\n\n
