NOVETROL

At Silicon Austria Labs (SAL), we are working on the complete cycle of a magnetoresistive device.

The project's goals are:

• Development of a fast, passive and self-regulating current limiter for DC grids
• Design and simulation of an InSB based magnetoresistive device to understand the limitations for current limiting applications
• Fabrication of an extraordinary magnetoresistance device based on bulk InSb
• Integration of fabricated samples in custom-designed Printed Circuit Boards (PCBs)
• Characterization of the magnetoresistive device (magnetoresistance, thermal and mechanical analysis)
• Achievement of a resistance variation over 1200 % under 1 T magnetic field
• Operation at maximum 60 °C temperature without active cooling

Within the project, SAL overcomes key challenges in sourcing and processing InSb while targeting operation close to room temperature. The project establishes European industrial leadership with technology that is critical for the ongoing energy transition and can be a breakthrough for DC circuit protection.
