Christie L.B., Schneider P., Oh K.W., University at Buffalo, US

The field of photoacoustics is increasing as new discoveries are being made showing potential for a system that is capable of higher resolution medical imaging, noninvasive vital monitoring, and cancer diagnostics. This research focuses on [...]

Additive Manufacturing of 3D Face Masks for Biometric Spoofing

Christie L., Mancuso K., Fedorishin D., Schneider P., Stone A., Oh K., University at Buffalo, US

Biometric security systems such as Apple’s FaceID have replaced passwords for mobile device security, leav- ing users susceptible to biometric spoofing attacks. In response, Apple has implemented an anti-spoofing scheme, looking for autonomous ocular movement [...]

Post-Processing Effects on 3D Dynamic Models Created from Additive Manufacturing

Fedorishin D., Stone A., Eadie N., Christie L., Schneider P., Oh K., University at Buffalo, US

Recent advancements in 3D printing have made it a more viable option for rapid and inexpensive modeling of three dimensional (3D) dynamic systems. This shift in modeling techniques comes with inherent issues. The rough finish [...]

Microfluidic Test Target for Photoacoustic Imaging

Schneider P., Eadie N., Christie L., Zhan Y., Siskar T., Koh D., Xia J., Oh K.W., University at Buffalo's Sensors & MicroActuators Learning Lab (SMALL), US

Photoacoustic imaging involves the use of optics (typically a high power pulsed laser) and acoustics (ultrasonics frequency ranges >1MHz) to image a targeted object. Individually, these modalities, being optical and ultrasonic imaging, can be quantified [...]

Additive Manufacturing of Microfluidic Components via Wax Extrusion

Schneider P., Sukhotskiy V., Christie L., Siskar T., Karampelas I.H., Furlani E.P., Oh K.W., University at Buffalo's Sensors & MicroActuators Learning Lab (SMALL), US

Fused deposition modelling (FDM) has been extensively applied in the fields of rapid prototyping and 3D printing, but typically this technique has mostly been used for the fabrication of low melting point plastics. This paper [...]

A compact syringe-assisted vacuum-driven micropumping with a constant flow rate

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

Abstract In this paper, a simple syringe-assisted pumping method was introduced. Compared with previous study [1], the proposed design does not require pre-designed vacuum chambers, the multiple pumps can be integrated into one device and [...]

3-D electrode configuration for electrochemical impedance spectroscopy of bulk solution

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

Abstract In this paper, a 3-D electrode configuration for electrochemical impedance spectroscopy (EIS) of a bulk solution was studied. Top- and bottom- electrode configuration, where two electrodes sandwich the sensing channel, was fabricated using the [...]

Combination of Analytical Models and Order Reduction Methods for System Level Modeling of Gyroscopes

Schneider P., Reitz S., Bastian J., Schwarz P., Döring C., Maute M., Neul R., Fraunhofer Institute for Integrated Circuits, DE

Within complex sensor systems different physical effects and electronics for signal processing have to be considered in the design process. In this paper we describe an approach for system level simulation of sensor systems and [...]

Stress Optimization of a Micromechanical Torsional Spring

Klose T., Kunze D., Sandner T., Schenk H., Lakner H., Schneider A., Schneider P., Schneider A., Schneider P., Fraunhofer IPMS, DE

In this paper we present a method for the design of a stress-optimized, micromechanical torsional spring, used in MEMS. Our optimization approach is based on a software tool for simulator-based optimization MOSCITO, cooperating with the [...]
