Competitive contact-less position sensor based on magnetoresistive nano-contacts

Objective

Sensors are essential devices in today's life, for example, current vehicles can contain more than 50-60 sensors and it is foreseen that the market for automotive sensors grow to around $12bn in 2010. Contact-less technologies for sensors show the best performance properties (duration and sensitive) though their price is much higher and their industrialization is much difficult because high technology equipments and installations are needed. The latest contact-less technology is based on Ballistic Magnetoresistance (BMR), a recently discovered phenomenon that shows magnetoresistance values of more than 1.000% (100 times higher than any other phenomenon observed so far) at nanocontact levels.

MUNDIS project will develop an angular position contact-less sensor, using an innovative approach to BMR based on the development of Multiple Nanocontact Devices (MUNDs), which will improve performance of current contact less sensors with lower price. The sensor developed will be validated in the automotive sector, for a specific application: an accelerator pedal position sensor with these features: Durable (>10.000.000cycles) Sensitive (>800mV/V FS), Cheap (market price < 5euros), Easy to industrialise.

Integration is a key factor in the project at three different levels:
- Systems: Nanoparticles - MUND (Sensitive part of the sensor) - Angular Position Contact less sensor - Accelerator pedal position sensor.
- Technologies: micro-tech, nano-tech, magnetism, chemistry, electronics, engineering.
- Partners: ACP, SME manufacturer, will be the future mass manufacturer of the new sensor. FICOSA, automotive multinational, will integrate and validate the sensor in its accelerator pedal system. INA, university, will be mainly responsible for nanocontacs development. CSIC-LFSP, will be responsible for MUNDs development. AGH, university, will characterise the nanocontacts. IP-PRAGUE, university, will characterise MUNDs at high pressure conditions.

Fields of science (EuroSciVoc)

CORDIS classifies projects with EuroSciVoc, a multilingual taxonomy of fields of science, through a semi-automatic process based on NLP techniques. See: The European Science Vocabulary.
