Development of a Chemically Resistant Coating for a novel Fiber Optic Temperature Sensor embedded in Lithium-ion Batteries

Rameez M.R., Ukata C., Ghannoum A., Nieva P., University of Waterloo, CA

Lithium-Ion batteries are ubiquitous in modern day life, with their market value set to reach more than USD 65 billion in 2023 [1]. Temperature is a key parameter in the safe operation of lithium-ion batteries [...]

Spectral engineering via complex patterns of rounded concave and convex nanoresonators achievable via integrated lithography realized by circularly polarized light

Sipos Á., Tóth E., Török A., Fekete O., Szabó G., Csete M., University of Szeged, HU

Comparative study has been performed on the spectral and near-field properties of complex concave and convex nano-object patterns that can be fabricated via interferometric illumination of colloid sphere monolayers (IICSM) by applying circularly polarized light. [...]

Controlling light diffraction with nanostructures

Tufaile A., Tufaile A.P.B., Vanderelli T.A., Snyder M., Tufaile A., Tufaile A.P.B., University of Sao Paulo, BR

We are presenting the main results of our research using smart fluids to control the light scattering using some devices based on nanotechnology. We are presenting the Ferrolens or Ferrocell®, which consists of a Hele-Shaw [...]

Large-Area Micro and Nanopatterned Drum Molds through Novel Nanocoining Process

Furst S., Miller N., Smart Material Solutions, Inc., US

Nanostructured surfaces have unique optical and wetting properties that can transform commercial products including OLEDs, biosensors, wire-grid polarizers, solar panels, and augmented and virtual reality headsets. Still, nanopatterning is generally limited to small-area, high-cost applications [...]

Solvent-free Printing of Organic Semiconductor, Insulator, Metal, and Conductor Particles on Flexible Substrates

Sakai M., Okada Y., Horiuchi Y., Suzuki M., Tomiya D., Chiba University, JP

Multi-material and solvent-free printing for printed electronics is developed using toner-type patterning of organic semiconductor, insulator, metal and other con- ductor particles, and the subsequent thin-film formation by ultrasonic sintering. Although conventional toner technology was [...]

Wearable IoT Devices for Health Monitoring

Bhat G., Tuncel Y., An S., Ogras U.Y., Arizona State University, US

Advances in wearable electronics pave the way for a new class of devices that combine sensing, process- ing, and communication. These devices enable a wide range of applications including health monitoring, ac- tivity tracking, and [...]

Chemical-Free Metal PDMS Thermal Bonding in Flexible Bio-Potential Electrode Fabrication

Koh D., Wang A., Oh K.W., University at Buffalo, US

The flexible bio-potential electrode is gaining signifiacnt interest in wearable or implantable biosensors. Among many soft materials, polydimethylsiloxane (PDMS) is widely studied because of its good biocompatibility and elasticity. However, due to the nature of [...]

Resistive Pressure Sensor with Carbon Nanotube Electrodes towards Flexible Electronics Applications

Palumbo A., Zhang R., Yan K., Yang E.H., Chen S., Hader G., Chang J., Yang E.H., Stevens Institute of Technology, US

Here, we present a flexible and stretchable pressure sensor composed of vertically aligned CNTs (VACNTs) partially embedded in a polydimethylsiloxane (PDMS) substrate. VACNTs were grown via chemical vapor deposition and transferred onto PDMS as a [...]

Compact Modeling of MEMS Contact Current upon Pull-In

Røst H.I., Clark J.V., Pister K.S.J., Auburn University, US

This work-in-progress presents a parameterizable compact model of a microelectromechanical system (MEMS) beam element that includes mechanical contact and electrical current flow upon gap closure. Quasistatic electromechanical simulation analyses include the initial onset of pull-in [...]

Wideband high-Q nonlinear resonance for MEMS

Clark J.V., Han Y., Abrol A., Zun Z., Auburn University, US

We examine high quality factor (Q) nonlinear wide- bandwidth resonance for microelectromechanical systems (MEMS) by mimicking high nonlinearity in stiffness by force feedback. The Q and bandwidth are usually thought of as being inversely proportional [...]
