Gedenkkolloquium für Alfred Seeger

Am 18. Oktober 2016 fand ein Gedenkkolloquium für Alfred Seeger statt, der genau ein Jahr zuvor verstorben war. Beim Gedenkkolloquium würdigten mehrere Sprecher die Person und die herausragenden wissenschaftlichen Leistungen von Herrn Seeger. Herrn Seegers Tochter Ulrike fand berührende Schlussworte. Prof. Trebin berichtete über seine persönlichen Erfahrungen bei der Zusammenarbeit mit Herrn Seeger. Alle diese Vorträge finden sich in der vorliegenden Gedenkseite. Die Anregung, ein Gedenkkolloquium zu veranstalten, kam von Prof. Urban. Es wurde dann i.W. von Prof. Trebin in Zusammenarbeit mit Prof. Kronmüller und Frau Stumpf vom MPI für Intelligente Systeme organisiert. [mehr]

Spirulina-templated Magnetic Helical Microswimmers for Biomedicine

In recent years, micro- and nanorobots have drawn lots of attention because of their promising potential in minimally invasive biomedical applications. Among them, magnetic helical swimming microrobots, inspired by E. coli bacteria, show interesting properties, such as precise remote actuation and 3-D navigation in a variety of fluidic environments using an external low-strength rotating magnetic field in vitro and in vivo. In this talk, Spirulina-templated helical swimming microrobots will be introduced, and their potential applications in biomedicine will be discussion. [mehr]

Fabrication and application of microtip electrode array using MEMS technology

  • Datum: 06.07.2016
  • Uhrzeit: 15:00 - 16:30
  • Vortragender: Prof. Dr. Seung-Ki Lee, Dept. of Electronics and Electrical Engineering, Dankook University, Korea (currently on sabbatical leave at ETH Zurich)
  • Seung-Ki Lee received the BS, MS, and PhD degrees in electrical engineering from Seoul National University, Seoul, Korea, in 1986, 1988, and 1992, respectively. His graduate research concentrated on design, fabrication, and characterization of silicon magnetotransistor. From 1992 to 1993, he was a JSPS Fellow with Tohoku University, Sendai, Japan, where he was involved in research on linear silicon microactuators using microelectromechanical system technology. In 1994, he joined the faculty of the department of electrical engineering, Dankook University, Gyeonggi-do, Korea, where he is currently a professor with the department of electronics and electrical engineering. From 2003 to 2004, he was a visiting professor with the Center for Intelligent Materials and Systems, University of Washington, Seattle, where he was involved in research on surface plasmon resonance (SPR) biosensors. He has conducted extensive research on medical applications of shape memory alloy actuators and electroactive polymers, biosensors using SPR, and microbial fuel cells using single cells.

With advances in micromachining technology, many microtip-type electrodes have been realized using three-dimensional techniques for the fabrication of micrometer-scale structures. Microtip electrodes are particularly attractive because of their sharpened features. These microtip-based electrodes have been applied to various applications such as field emission displays, scanning tunneling microscopy, scanning electrochemical microscopy, intracellular recording and physiological signal. Our microtip array have high aspect ratio, small apex radius and covered with insulated layer except the tip ends. It has been introduced to fabricate microtip array that a combination of DRIE(anisotropic etching) and RIE(isotropic etching) processes with varying the gap and diameter of the etch masks [1]. Besides the fabrication and various applications of microtip electrodes [2], a short summary of current research topics in our group such as fiber optic localized surface plasmon resonance sensor, microsensor array for dissolved oxygen, photosynthetic microbial fuel cell, LIDAR using micromirrors, wafer-level packaging and actuators using shape memory alloy and electroactive polymer will be introduced in this talk.
