Development of Quantitative Adhesive Force Measurement Systems for Flexible Electronics

Kim M., Park J., Choi B., Sogang University, KR

In this paper, a novel adhesive force measurement system is developed to measure adhesive forces from interacting surfaces. In previous paper, the adhesive force was measured with tens/hundreds of uN, and the displacement was measured [...]

Design and Fabrication of the Sensor for Measuring the Human Bladder Volume

Lee S., Jun S., Kim S., Kim S., Choi B., Sogang University, KR

This paper presents the result of study on the development of a bladder volume sensor. Previous studies focus on the development of an inner bladder pressure sensor. But there are some difficulties about the measurement [...]

Energy Conversion according to Impact loading on Piezoelectric material

Lee J., Kim T., Choi B., Sogang University, KR

Energy harvesting using piezoelectric material has been one of the hottest interests in powering wireless sensor nodes without maintenance and replacement of wired or battery power system in ubiquitous era. Unlike most of the previous [...]

A Study on the Novel Type of Ferrofluid Magnetic Pipette

Ahn J.J., Oh J., Choi B., Sogang University, KR

This study was performed to design the novel type of ferrofluid magnetic pipette on a micro scale for the purpose of applications to delivery systems, which is the core device of Lab on a chip [...]

Thermal and Load-Deflection FE Analyses of Parylene Diaphragms

Sim W., Kim B., Choi B., Park J-O, Intelligent Microsystem Center, KR

In this study, the finite-element method(FEM) is employed in order to analyze the mechanical behavior of parylene diaphragm. Thermal and load-deflection FE analyses of flat and corrugated parylene diaphragm are performed to find an effect [...]
