For employing micro antenna structure to TFT, the magnetic core (MC) is added to the micro antenna structure to enhance the delivered wireless power and signal due to the decrease of the power efficiency as the scale down of antenna size. The MC is consisted of ZnO nano-wires and Ni, a ferromagnetic material, which is coated on the vertical ZnO nano-wires. Due to the increase of self-resonance frequency with decreasing antenna size, we choose and fabricated a-IGZO TFT, which can have a higher mobility than a-Si TFT.

Our device employs a highly flexible magnetic composite polymer (M-CP) for actuation of a flexible microchannel system. We combine our M-CP with micropatterned non-magnetic polydimethylsiloxane (PDMS), resulting in flexible microsystems with integrated actuators and microfluidic channels whereby we can optically visualize cells in order to monitor various aspects of cell behavior including migration, proliferation, and morphological changes. The M-CP can be rendered permanently magnetic, so it can be employed for both substrate tension and compression using the same electro- or permanent magnet with pole reversal. We have demonstrated proof-of-concept of an instrument designed to simultaneously stimulate ECs grown in microfluidic channels with both fluid flow and mechanical stretch/compression using the new M-CP actuators.","PeriodicalId":367660,"journal":{"name":"14th IEEE International Conference on Nanotechnology","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115702319","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 thin micropipettes were prepared and their spring constant was measured using the Atomic Force Microscopy (AFM) cantilever before stiffness measurement. The deformation of the pipette tips and the cell were observed under an optical microscope. The cell stiffness was calculated from the deformations based on the Hooke's low. The measurement results show that the myoblast C2C12 cell on a glass substrate has the stiffness around 0.1 N/m.

Printing and functionalizing these IDC sensors on bendable substrates will lead to new innovations in healthcare and medicine, food safety inspection, environmental monitoring, and public security. The synthesis of an electrically conductive aqueous graphene ink stabilized in deionized water using the polymer Carboxymethyl Cellulose (CMC) is introduced in this paper. CMC is a nontoxic hydrophilic cellulose derivative used in food industry. The water-based graphene ink is then used to fabricate IDC sensors on mechanically flexible polyimide substrates. The capacitance and frequency response of the sensors are analyzed, and the effect of mechanical stress on the electrical properties is examined. Experimental results confirm low thin film resistivity (~6;.6×10-3 Ω-cm) and high capacitance (>100 pF).

The semiconducting MoS2 as n-channel and few-layer phosphorene as p-channel have been considered as promising ultra-thin body channels for future microelectronic and optoelectronic devices. In this paper, we focus on the fundamental device properties in these 2D transistors. In the first part we introduce the dielectric integration on MoS2 and other 2D crystals by atomic layer deposition, revealing the similarities and differences of dielectric integration on bulk and 2D crystals. Then we present the different metal contacts on MoS2, showing Fermi level pinning at metal/2D interfaces. Through molecular chemical doping, contact resistance to MoS2 is able to be reduced to 0.5 Ω·mm and high-performance MoS2 FETs with drain current of 460 mA/mm are demonstrated. Then we discuss scaling of channel length and width of MoS2 transistors. Finally we demonstrate a 2D CMOS inverter with a MoS2 NFET and a few-layer phosphorene PFET, showing the potentials on these 2D crystals for heterogeneous device integrations.","PeriodicalId":367660,"journal":{"name":"14th IEEE International Conference on Nanotechnology","volume":"82 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132951517","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}

According to theoretical prediction, the solar-to-hydrogen efficiency of hematite can be 16.8% and the water splitting photocurrent can be 12.6 mA cm-2. However, the practical performance of hematite for solar water splitting is far from the ideal case which has been limited by several factors such as poor conductivity, short lifetime of the excited-state carrier (10-12s), poor oxygen evolution reaction (OER) kinetics, short hole diffusion length (2-4nm), and improper band position for unassisted water splitting. In our recent work, enormous efforts have been focused on improving the performance of hematite nanostructure photoelectrode. Different methods such as morphology control, elemental doping, and improvement of the charge transport of hematite have been developed to improve the performance of hematite photoelectrode in solar water splitting.","PeriodicalId":367660,"journal":{"name":"14th IEEE International Conference on Nanotechnology","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121416058","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}
