- Low field magnetoimpedance in the GHz range
[作者:de Cos, D; Alvarez, G; Garcia-Arribas, A; Montiel, H; Barandiaran, JM; Zamorano, R; Valenzuela, R,期刊:Sensors And Actuators A-Physical, 页码:485-490 , 文章类型: Article,,卷期:2008年142-2]
- In this paper we investigate different aspects of the high-frequency magnetoimpedance at low fields. In the first place, we will study this effect from a phenomenological point of view, comparing it with the low-frequenc...
- Contactless flow detection with magnetostrictive bilayers
[作者:Traxler, S; Kosel, J; Pfutzner, H; Kaniusas, E; Mehnen, L; Giouroudi, I,期刊:Sensors And Actuators A-Physical, 页码:491-495 , 文章类型: Article,,卷期:2008年142-2]
- The paper concerns the contactless detection of an airflow through a tube by the use of a magnetostrictive bilayer strip as a sensor element. A bilayer mounted in the tube is magnetized by an exterior excitation coil. Du...
- An ac/dc magnetometer for space missions: Improvement of a Hall sensor by the magnetic flux concentration of the magnetic core of a searchcoil
[作者:Leroy, P; Coillot, C; Mosser, V; Roux, A; Chanteur, G,期刊:Sensors And Actuators A-Physical, 页码:503-510 , 文章类型: Article,,卷期:2008年142-2]
- Theoretically, the sensitivity of Hall sensors can be improved by at least three orders of magnitude by implementing them into an especially tailored magnetic concentrator [P. Leroy, C. Coillot, A. Roux, G. Chanteur, Hig...
- Sensor system for early detection of heart valve biop rostheses failure
[作者:Rivero, G; Garcia-Paez, JM; Alvarez, L; Multigner, M; Valdes, J; Carabias, I; Spottorno, J; Hernando, A,期刊:Sensors And Actuators A-Physical, 页码:511-519 , 文章类型: Article,,卷期:2008年142-2]
- Heart valve bioprostheses usually do not need anticoagulation; however, they are threatened by an increasing time risk of degeneration. The aim of this work is to find a magnetic sensor, which could be integrated in a bi...
- Wireless magnetic motion capture system using multiple LC resonant magnetic markers with high accuracy
[作者:Hashi, S; Toyoda, M; Yabukami, S; Ishiyama, K; Okazaki, Y; Arai, KI; Kanetaka, H,期刊:Sensors And Actuators A-Physical, 页码:520-527 , 文章类型: Article,,卷期:2008年142-2]
- The present paper reports the principle of a wireless magnetic motion capture system that uses multiple LC resonant magnetic markers and demonstrates its application. Small and lightweight markers (4 mm in diameter, 10 m...
- High magneto striction polymer-bonded Terfenol-D composites
[作者:Rodriguez, C; Barrio, A; Orue, I; Vilas, JL; Leon, LM; Barandiaran, JM; Ruiz, MLFG,期刊:Sensors And Actuators A-Physical, 页码:538-541 , 文章类型: Article,,卷期:2008年142-2]
- Different magnetostrictive composites that contain Terfenol-D particles in a polyurethane elastomer matrix were prepared by changing the ratio of the hard/soft segment (F) of the polyurethane, and modifying the amount of...
- A 3D micromechanical compass
[作者:Kyynarainen, J; Saarilahti, J; Kattelus, H; Karkkainen, A; Meinander, T; Oja, A; Pekko, P; Seppa, H; Suhonen, M; Kuisma, H; Ruotsalainen, S; Tilli, M,期刊:Sensors And Actuators A-Physical, 页码:561-568 , 文章类型: Article,,卷期:2008年142-2]
- We have designed and fabricated micromechanical magnetometers intended for a 3D electronic compass which could be embedded in portable devices. The sensors are based on the Lorentz force acting on a current-carrying coil...
