A Framework for Associating Mobile Devices to Individuals Based on Identification of Motion Events
DownloadFall 2020
The ubiquity of the Internet-of-Things (IoT) devices in everyday life allows various sensors to be utilized in networked systems for solving a number of real-world problems. Models utilizing specific sensing modalities achieve impressive performance in understanding human activity and are used in...

Zhang, Qiang, Serpe, Michael J.
A versatile surface modification technique was developed to yield poly(N-isopropylacrylamide) (pNIPAm) microgel-based thin films on a variety of substrates, e.g., metals, nonmetals, and polymers. Because the chemistry, and hence functionality and responsivity, of the pNIPAm-based microgels is...

The fluid mechanics literature suggests that the ability to manipulate the very-large-scale motions (VLSMs) that exist within turbulent boundary layers (TBLs) would provide influence over the unwanted drag forces, noise, and vibrations associated with these flows. The ability to suppress these...

Johnson, Kai C. C., Mendez, Francisco, Serpe, Michael J.
Poly (N-isopropylacrylamide)-co-acrylic acid (pNIPAm-co-AAc) microgel-based etalons have been shown to have visible color and unique spectral properties, which both depend on solution temperature and pH. In this investigation, pNIPAm-co-AAc microgel-based etalons were fabricated on the Au...

Zhang, Wei, Wei, Menglian, Carvalho, Wildemar S. P., Serpe, Michael J.
A biosensor for mouse Immunoglobulin G (IgG) was generated from responsive polymer-based interference filters (etalons). To accomplish this, an excess amount of alkaline phosphatase-modified goat anti-mouse IgG (AP-GAM, F(ab’)2 fragment specific to mouse IgG) was added to mouse IgG, and allowed...

Flexible electronics integrate functional electronic devices on paper and plastic substrates and fill niches complementary to silicon electronics in applications where bending and stretching of devices are required or preferred. Yet, most flexible devices are still more or less facing performance...

Developing miniature instrumentation for biosensing has attracted an extensive interest due to the demand for selective and sensitive detection of multiple targets at extremely low concentrations with exceedingly small sample volumes. Micro/nano mechanical sensors, such as microcantilevers (MCL),...
