PI Offers Capacitive Sensor Tutorial

A free brochure featuring a tutorial on single- and dual-plate capacitive sensors and applications is available from PI (Physik Instrumente), an Auburn, Mass. maker of ultraprecision motion control and sensing equipment for biotechnology, nanotechnology, photonics, semiconductor and life science applications. Capacitive sensors perform high-precision, noncontact measurements of geometric quantities representing displacement, separation, position, length or other linear dimension against any kind of electrically conductive target. The brochure features overviews on these topics: measuring displacement with nanometer precision; nanopositioning, closed-loop systems; parallel metrology, high-precision multi-axis measurements; measuring straightness and flatness, active cross-talk compensation; out-of-plane measurement, constant-height scans, out-of-round measurement; tip-tilt measurement and compensation; measuring vibration, flatness, thickness; force sensors with micronewton sensitivity; and layer thickness measurement with submicron accuracy. It may be ordered from PI or can be downloaded at: www.physikinstrumente.com/en/products/capacitive_sensor/index.php

Glossary

metrology: Metrology is the science and practice of measurement. It encompasses the theoretical and practical aspects of measurement, including the development of measurement standards, techniques, and instruments, as well as the application of measurement principles in various fields. The primary objectives of metrology are to ensure accuracy, reliability, and consistency in measurements and to establish traceability to recognized standards. Metrology plays a crucial role in science, industry,...
nano: An SI prefix meaning one billionth (10-9). Nano can also be used to indicate the study of atoms, molecules and other structures and particles on the nanometer scale. Nano-optics (also referred to as nanophotonics), for example, is the study of how light and light-matter interactions behave on the nanometer scale. See nanophotonics.
nanotechnology: The use of atoms, molecules and molecular-scale structures to enhance existing technology and develop new materials and devices. The goal of this technology is to manipulate atomic and molecular particles to create devices that are thousands of times smaller and faster than those of the current microtechnologies.
photonics: The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
