Indoor Navigation of Emergency Agents

Bertrand Merminod, Phillip Tomé, Okan Yalak

Existing indoor navigation solutions usually rely on pre-installed sensor networks, whereas emergency agents are interested in fully auto-deployable systems. In this paper, an almost self-deployable solution based on Radio-frequency identification tags and ...

Fabrication of metallic patterns by microstencil lithography on polymer surfaces suitable as microelectrodes in integrated microfluidic systems

Jürgen Brugger, Marc Antonius Friedrich van den Boogaart, Nao Takano, Helmut Knapp

Microstencil lithography, i.e. local deposition of micrometer scale patterns through small shadow masks, is a promising method for metal micropattern definition on polymer substrates that cannot be structured using organic-solvent-based photoresist technol ...

Improved design of a silicon micromachined gyroscope with piezoresistive detection and electromagnetic excitation

Nico de Rooij

In this paper, an improved design of a silicon micromachined gyroscope (angular rate sensor) is presented. It is based on the tuning fork principle and realized by combining two proof masses. The gyroscope is driven by electromagnetic forces and detects th ...

Thin film pyroelectric arrays as infra-red detectors

Paul Muralt, Andreas Seifert

Pyroelectric thin film 12-element linear arrays (element size 0.4x0.9 mm(2)) have been fabricated by standard photolithography techniques on silicon substrates. A voltage responsivity of almost 800 V/W in air and 3000 V/W in vacuum is measured at low frequ ...
