The Wiegand effect is a nonlinear magnetic effect, named after its discoverer John R. Wiegand, produced in specially annealed and hardened wire called Wiegand wire. Principle of a Wiegand sensor and external magnetic field. Wiegand wire is low-carbon Vicalloy, a ferromagnetic alloy of cobalt, iron, and vanadium. Initially, the wire ...
17 de oct. de 2022 · El protocolo Wiegand, también llamado comúnmente interfaz Wiegand, es un estándar de cableado que se encuentra en lectores de tarjetas y sistemas de control de acceso, y se ha convertido en el método de comunicación de facciones más común para dichos sistemas desde la década de 1980.
17 de oct. de 2022 · This review paper is divided into subsections including the working principles and the reversal behaviors of the Wiegand effect; the improvement of output properties regarding the materials, manufacture, and circuits; and the scenarios in which sensing magnetic fields occur.
1 de ago. de 2011 · The Wiegand effect, a phenomenon discovered in the 1970s, is the unusually useful behavior of magnetic fields in specially designed wire that outputs voltage. This Wiegand...
31 de ene. de 2022 · El efecto Wiegand consiste en un fenómeno magnético no lineal; su nombre se debe a John R. Wiegand, su descubridor durante la década de 1970.
11 de may. de 2022 · In this article we describe an Internet-of-Things sensing device with a wireless interface which is powered by the often-overlooked harvesting method of the Wiegand effect. The sensor can determine position, temperature or other resistively measurable quantities and can transmit the data via an ultra-low power ultra-wideband (UWB ...
Wiegand sensors are magnetic sensors that do not need any external voltage or current, and make use of the Wiegand effect to generate a consistent pulse every time magnetic field polarity reverses.
