High-Sensitivity and Low-Hysteresis Inter-digital Type Capacitive Humidity Sensor on Glass Substrate by Aerosol Deposited BaTiO3

Kim E.S., Kim N.Y., Wang C., Wang Z.J., Wang C., Wang Z.J., Yao Z., Liang J.G., Kim E.S., Kim N.Y., Kwangwoon University, KR

A high-sensitivity and low-hysteresis inter-digital type capacitive humidity sensor is fabricated using Aerosol deposition (AD) of BaTiO3 films. Aerosol deposition (AD) uses shock-loading-solidification preparation mechanism as a novel ceramic film preparation technique, exhibiting the advantages [...]

Reusable Biosensor for Detecting Diabetes by Microwave LC Resonator on Integrated Passive Design (IPD) Process

Kim E.S., Kim N.Y., Chuluunbaatar Z., Wang C., Yao Z., Adhikari K.K., Kim E.S., Kim N.Y., Kwangwoon University, KR

This works present a level-free biosensor for detecting diabetes with high sensitivity and rapidity by microwave LC resonator based on integrated passive device (IPD) technology. The structure of the proposed consists of the square meandered [...]

In-Transit Visibility and Total Asset Visibility for Cold Chain Supply Logistics

McCleland B., Russell T.W., Myconi Technologies, US

Thousands of temperature sensitive products that require continual monitoring and controls are shipped every day. Last year, temperature-compromised pharmaceutical products cost the industry $35.0 billion. Almost 30% of products in the perishable food market were [...]

SERS Detection of DNA-Bound Methylthioninium Chloride on Gold Coated Substrates.

Shattique M.R., Stepanova M., Missouri State University, US

Nano-biological systems interfacing solid nano-structured solid surfaces with biological compounds such as oligonucleotides or proteins are highly regarded as enabling materials for biosensing and biocatalysis applications. In particular nanostructures of noble metals such as gold [...]

Beyond Visualization – Vivid Frameworks for Ubiquitous Sensor Data

Paradiso J., Massachusetts Institute of Technology, US

We have already witnessed profound and often unanticipated developments as IoT is built out and the world is mediated via mainly graphical wireless devices held at arm’s length. But what will happen once the world [...]

Myconi Technical Solutions for In Transit Visibility Cold Chain Logistics

McCleland B., Russell T.W., Myconi Technologies, US

Myconi Technologies has developed a proprietary wireless, ad hoc, peer-to-peer, self-healing mesh network protocol that operates on internationally license-free frequencies (IEEE 802.15.4 ISM Standard). Myconi has incorporated this wireless technology with multiple environmental and material [...]

Silicon Nanowire Vertical Arrays with Porous Top Electrodes for Trace Vapor Preconcentration and Partial Separation

Giordano B., Pehrsson P., Johnson K., U.S. Naval Research Laboratory, US

Commercial Off the Self (COTS) technologies for chemical vapor detection of trace analytes in complex, unknown background environments, often underperform with respect to sensitivity and selectivity. We have developed a chemical preconcentrator based on a [...]

Micro-Sized Power Controllers for Space

Frohling K., Iris Technology, US

The explosion in SmallSat and CubeSat deployments has led to a need for miniaturized cooling solutions for sensors that require cooling. Since there are limited opportunities for miniaturization in the thermal mechanical unit (TMU) portion [...]
