Laparoscopic Manipulation of a Probe-based Confocal Laser Endomicroscope Using a Steerable Intravascular Catheter

Probe-based confocal laser endomicroscopy is an emerging imaging modality that enables visualization of histologic details during endoscopy and surgery. A method of guiding the probe with millimeter accuracy is required to enable imaging in all regions of the abdomen accessed during laparoscopy. On the basis of a porcine model of laparoscopic liver resection, we report our experience of using a...

Ultra-slim plastic endomicroscope objective for non-linear microscopy

Non-linear microscopy has the potential to provide clinically useful information on the structure of biological tissue in vivo via an endomicroscope. The ability to use plastic as the optical material in a multiphoton objective was evaluated based on several criteria including autofluorescence, injection molding induced birefringence, and pulse broadening due to group velocity dispersion. An al...

Ultra-thin Silicon Chips in Flexible Microsystems

With the growing demand for mechanically flexible electrical systems and the increasing level of integration of electrical assemblies, hybrid build-ups combining polymer substrates and ultra-thin flexible silicon chips (system-in-foil) are getting more and more important. These systems need thin chips which maintain their functionality even in bent condition as well as reliable handling and ass...

Ultra-Compact Bidirectional Terahertz Switch Based on Resonance in Graphene Ring and Plate

In this paper, we present a switch based on coupling and resonance in thegraphene plate and rings operating at 10 THz. This structure consists of several layers ofHexagonal Boron Nitride (hBN), SiO2 and P+Si, such that graphene plates and rings areinside the hBN layer. The terahertz wave is incident from the upper part of the switchand Surface Plasmons (SPs) are excited ...
