The processes involve printing silver electrodes on PET film using large-area screen printing, and soaking flexible papers in PEDOT: PSS aqueous dispersion. Then, papers are cut into square shaped pieces with a specific size using UV laser after drying to serve as the pressure sensing layer. The pressure sensing layers are laminated by the upper and lower electrodes to form a sandwich structure and sealed using a heat-sealing roller for thermoplastic packing. Multiple sensors are then cut and separated using UV laser. The process yields approximately 48 sensors per hour with a thickness of 0.16 mm, providing great flexibility for conformal attachment. These sensors have piecewise linearities over a pressure sensing range up to 325 kPa. They also exhibit fast excellent response time (25 ms) and recovery time (40 ms), good stability under the conditions of 2.5 Hz frequency response and 1000 cycles of loading and unloading. The simple and rapid manufacturing process makes these sensors highly promising for various applications such as robotic tactile sensing and wearable healthcare.","PeriodicalId":142575,"journal":{"name":"2023 IEEE 18th International Conference on Nano/Micro Engineered and Molecular Systems (NEMS)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116483001","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A multilayered EMI shielding composite was synthesized through an elaborate multistep process, with the epoxy resin positioned in the upper and lower layers as the protective coating and a multilayered nanocomposite film, composed of Fe3O4 nanoparticles, polythiophene (PTh) nanofiber arrays, and an Au nanofilm, embedded in the middle layer. The favorable combination of magnetic nanoparticles and conducting polymer (CP) nanofiber arrays resulted in an EMI shielding effect (EMI SE) of over 30 dB when Fe3O4 was used in moderate amounts, surpassing the EMI SE of the PTh nanofiber arrays/Au/epoxy resin EMI shielding composite (~23 dB) prepared through a similar process, but without the immersion in Fe3O4 nanoparticle dispersion. The improved EMI SE is attributed to the incorporation of magnetic nanoparticles, which enhanced the impedance mismatch between the arrays and air, and introduced magnetic losses that further attenuate the EM waves. This novel, lightweight, thin, multilayered EMI shielding nanocomposite film exhibits excellent EMI shielding performance and holds great potential for use in EMI shielding and protection for high-powered electronic devices.","PeriodicalId":142575,"journal":{"name":"2023 IEEE 18th International Conference on Nano/Micro Engineered and Molecular Systems (NEMS)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121182892","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The spraying method is easy to operate, low-cost, high-efficiency and can be used to prepare flexible electrodes in a large scale. The sprayed silver nanowires on graphene film can overcome the poor electrical contact behavior of the pristine silver nanowire network due to the high roughness and weak physical contact between the film and the underlying substrate. This results in a conductivity of composite electrode four times that of the silver nanowire film. After 10,000 mechanical bending cycles, the resistance of the silver nanowire film increases about 92%, while the change in the composite electrode is only 4%, indicating a dramatically improved mechanical flexibility. The presence of the graphene film prevents the oxidation of silver nanowires and the failure caused by external forces. The composite electrode demonstrates excellent moisture resistance and their electrical resistance remains stable in a wide humidity condition from 35% to 95% relative humidity. In contrast, the resistance of the pristine silver nanowire film almost doubled because of wetness. Moreover, the composite electrode possesses better light transmission compared to commercial indium tin oxide electrodes. The combined good conductivity and high transmittance show great advantages in flexible display applications and potentiality for replacing the commercialized ITO film.","PeriodicalId":142575,"journal":{"name":"2023 IEEE 18th International Conference on Nano/Micro Engineered and Molecular Systems (NEMS)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125275555","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, focused ion beam (FIB) is employed to fabricate nanopores with similar sizes on these two-dimensional (2D) materials to compare their performance in sequencing DNA. According to our experimental results, graphene nanopores have a stronger interaction with DNA than MoS2, which contributes to a better temporal resolution. However, in the low-frequency region, the 1/f noise level of MoS2 is obviously lower than that of graphene. Furthermore, the nanopore was fabricated on graphene and MoS2 heterostructure for DNA sequencing, and the translocation events were successfully captured. It is demonstrated that the new heterostructure reduces the high noise level in the low-frequency region of graphene nanopores in DNA sequencing. It is expected that graphene and MoS2 can complement each other and facilitate the realization of single-base detection resolution in the future.","PeriodicalId":142575,"journal":{"name":"2023 IEEE 18th International Conference on Nano/Micro Engineered and Molecular Systems (NEMS)","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134491788","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
