However, the inherent hysteresis nonlinearity between the input current and the output displacement seriously limited the application of the MSMA-based actuator. In this paper, the hysteresis, which is related to the input frequency and working condition (such as load), is analyzed. Then a mathematical modeling method using Duhem model (DM) and Takagi-Sugeno fuzzy neural network (TSFNN) is introduced to describe the hysteresis behavior. The mathematical expression of the DM is explicit and simple; and the TSFNN, which has the advantages of both fuzzy system and NN structure, is used to identify the DM parameter. Hence, the proposed TSFNN-DM method has the merits of self adjustment and clear expression. To certify the validity of the developed model, comparative experiments with the modeling methods in other literatures are executed. Experimental results confirm that the TSFNN-DM has the better modeling performance to depict the hysteresis under the different input frequencies and loads than other modeling methods in previous studies.","PeriodicalId":6787,"journal":{"name":"2020 IEEE 15th International Conference on Nano/Micro Engineered and Molecular System (NEMS)","volume":"10 1","pages":"77-82"},"PeriodicalIF":0.0,"publicationDate":"2020-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89156104","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 idea is to locally disrupt cell membrane for allowing cargo passage into the cytosol such as to create its therapeutic effect. Till to date, most of the intracellular delivery is performed in bulk approaches, which provides an average ensemble data, losing low-frequency rare information. Besides, reliable results require huge data from multiple cells. Hence, to ensure huge data on individual cells it becomes necessary to carry out delivery experiments on a large number of single-cells simultaneously. This ensures the same experimental conditions conserving heterogeneity in the cell population. The collection of data from individual cells provides information about rare low-frequency alleles in the cell population. Massively parallel delivery ensures such uniform experimental conditions with uniform cargo delivery to a large number of individual cells. The proposed device platform is an array of photothermal Micro-dish patterned with fibronectin protein to obtain specific Single-cell attachment. The device can deliver 10,000 individual cells with 97% efficiency and 95% cell viability simultaneously.","PeriodicalId":6787,"journal":{"name":"2020 IEEE 15th International Conference on Nano/Micro Engineered and Molecular System (NEMS)","volume":"16 1","pages":"320-324"},"PeriodicalIF":0.0,"publicationDate":"2020-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90433705","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 regards, a variety of methodologies have been reported in the field of device and electrode manufacturing, and dedicated enzyme immobilization chemistry. However, the lower power output, shorter enzyme life, and high operating and maintenance overheads are key barriers to the commercialization of EBFCs. Here, easily fabricated and cost-efficient printed circuit board (PCB) electrodes, patterned with multi-walled carbon nanotubes (MWCNT), have been presented. These bioelectrodes were further positioned over a Y-shaped PDMS microchannel and tested under microfluidic environment. The electrodes were further immobilized with GOx and laccase enzymes, to behave as anode and cathode respectively, and voltammetric electrochemical performance was established with respective electrolytes (glucose and oxygen).

It is the primary metabolically produced acid responsible for tissue acidosis that can lead to muscle fatigue. During intensive exercise, the muscles go through anerobic metabolism to produce energy. This leads to decreases in the blood flow of nutrients and oxygen to the muscles and increases in lactate production, which in turn cause lactic acidosis. Currently, changes in blood lactate concentrations are monitored by sensors that can be invasive via blood or wearable based sensors that use the enzyme lactate oxidase. Lactate oxidase produces hydrogen peroxide, which is a toxic byproduct and can foul the surface of the sensor. Here we present the development of a noninvasive wearable electrochemical lactate biosensor for the detection of lactic acid. This work presents the development of non- invasive wearable electrochemical lactate biosensor for detection of lactic acid. The bioelectrode comprised D-Lactate dehydrogenase (D-LDH) immobilized on multi-walled carbon nanotubes (MWCNTs) using polydimethylsiloxane (PDMS) as a flexible substrate platform. The lactate biosensor exhibited a dynamic linear range of 2 mM to 44 mM lactic acid with a good sensitivity of 189.89 μA/mM cm2. This electrochemical biosensor has the potential to be used for the real-time detection of lactate in the clinical, biological and sports medicine fields.","PeriodicalId":6787,"journal":{"name":"2020 IEEE 15th International Conference on Nano/Micro Engineered and Molecular System (NEMS)","volume":"7 1","pages":"580-583"},"PeriodicalIF":0.0,"publicationDate":"2020-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82484974","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}
