Exchange-biased planar Hall effect sensor optimized for biosensor applications

Piezo Voltage Controlled Planar Hall Effect Devices

The electrical control of the magnetization switching in ferromagnets is highly desired for future spintronic applications. Here we report on hybrid piezoelectric (PZT)/ferromagnetic (Co2FeAl) devices in which the planar Hall voltage in the ferromagnetic layer is tuned solely by piezo voltages. The change of planar Hall voltage is associated with magnetization switching through 90° in the plane...

Hall Effect Sensor for Measuring Metal Particles in Lubricant

This paper presents the development of hall effect sensor for measuring the contamination of lubricant in industry. This technique is based on the principle of the magnetic field and Hall Effect. The magnetic field is made up of a permanent magnet which is measured by a Hall Effect sensor. The measured magnetic field can be estimated the level of contaminants in the oil by the ferrous particles...

Modeling Ion Sensitive Field Effect Transistors for Biosensor Applications

During recent decades increasing interest has been shown in the development of biosensors based on ion sensitive field effect transistors (ISFETs). Many ISFET– based pH sensors have been already commercialized and attempts have also been made to commercialize ISFETbased biosensors for applications in the fields of medical, environmental, food safety, military and biotechnology areas. The growin...
