For the first time, preferential cells differentiation on a technical surface into functional myotubes is demonstrated. The micro-scaffolds are based on concatenated bowtie elements fabricated by two-photon lithography and designed to achieve an equivalent Young's modulus of 12kPa. The high flexibility promotes the differentiation of the muscle cells into contractile myotubes [1]. Compared to state-of-the-art gel-based cell culture substrates, mechanical metamaterials can be shaped into arbitrary complex 3D geometries opening pathways towards muscle-driven biohybrid MEMS.","PeriodicalId":157312,"journal":{"name":"2016 IEEE 29th International Conference on Micro Electro Mechanical Systems (MEMS)","volume":"118 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-02-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133780256","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}

Optical modulation is observed at the device resonance frequency of 843 MHz. The device could be used for signal modulation in RF-Photonic systems.

The output performance can be improved by optimizing the size of the flapping leaf and the connecting position between the cantilever and leaf. At a wind speed of 4.5 m/s, the maximum power of the piezoelectric and triboelectric parts of one-side FLMG can be obtained as 8.1 μW and 13.6 μW at optimized load resistances of 1 MΩ and 0.75 MΩ, respectively.","PeriodicalId":157312,"journal":{"name":"2016 IEEE 29th International Conference on Micro Electro Mechanical Systems (MEMS)","volume":"332 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-02-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122989237","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}

These novel devices are identified as Cross-Sectional-Lamé-Mode resonators (CLMRs) as they rely on the piezoelectric transduction of a Lamé mode, in the cross-section of an AlN plate. Such 2-dimensional (2D) mechanical mode of vibration, characterized by motion along both the lateral and the thickness directions, is actuated and sensed piezoelectrically through the coherent combination of the en and en piezoelectric coefficients of AlN. This special feature enables the implementation of CLMRs with high values of electromechanical coupling coefficient (kt2). We demonstrate a kt2 value in excess of 4.6% in a CLMR operating around 1.02 GHz. Such kt2 value is the highest ever reported among AlN resonators employing interdigital-metal-electrodes (IDTs) to actuate and to sense the mechanical motion.","PeriodicalId":157312,"journal":{"name":"2016 IEEE 29th International Conference on Micro Electro Mechanical Systems (MEMS)","volume":"373 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-02-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116626887","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}
