Nanoscale Integrated Magnetic Field Sensor

Descripción del proyecto

Optimización de los sensores de campos magnéticos para su uso en aplicaciones más industriales

Desde el transporte hasta la medicina, los sensores magnetorresistivos son un tipo de sensor de campos magnéticos que se ha hecho omnipresente. Diseñados para detectar un campo magnético aplicado, estos componentes de bajo coste son pequeños y funcionan con muy poca energía. Sin embargo, varias limitaciones les impiden alcanzar todo su potencial en una amplia gama de aplicaciones. Financiado por el Consejo Europeo de Investigación, el equipo del proyecto NANOSENSE pretende basarse en la prueba de concepto de un sensor de campos magnéticos que ya se ha propuesto y patentado. Demostrará las excelentes prestaciones del sensor y, a continuación, procederá a su comercialización y a la concesión de licencias a un fabricante de sensores.

Objetivo

Magnetic sensors are present everywhere in our daily lives. We often use them in cars, robotics, medical applications, for power sensing, electronic compass, etc. Among them, magnetoresistive sensors play an increasing role thanks to their relatively small size, good sensitivity and low cost. However, magnetoresistive sensors saturate above typically a few milli-Tesla which is too low for a number of applications. Besides, reducing the sensor footprint is important in terms of costs. In addition, smaller sensors have also a reduced power consumption which is very important for wearable applications and sensors used in Internet of Things. Therefore, it is commercially desirable to be able to develop a low cost, nano-size, magnetoresistive sensor in which the dynamic range could be extended and easily adjusted in the range 80mT-400mT commonly used in linear or angular encoders.
Within an ERC project which just ended entitled CMOS/Magnetoelectronic Integrated Circuits
with Multifunctional Capabilities, a novel concept of magnetic field sensor sensitive to out-of-plane field was proposed and patented. Initial experiments performed within this ERC project provided very promising results. The purpose of this ERC project is to make a full proof of concept of this sensor demonstrating its outstanding performance and subsequently move towards a start-up creation or licensing of the technology to an existing sensors manufacturer. Within NANOSENSE, we aim to achieve gains over existing sensors by 10x in terms of footprint reduction, 50x in power consumption, 10x in signal to noise ratio while increasing the sensing range up to ~800mT. This will make these sensors suitable for integration in sensors network for IoT, sensors for wearable applications, automotive, detection of leakage current in electronic circuits, detection of microcracks in metals, navigation of surgical tools (e.g.endoscopes).
