Prof. Susana Cardoso

Magnetoresistive (MR) biochips are evolving quickly into compact, high‑performance platforms for sensitive biomolecular detection. Current efforts emphasize refining both the device architecture and the dynamic response, while preserving a minimal overall system footprint that includes the electronics, microfluidics, excitation elements, and the MR sensor chip. This presentation will examine different chip‑layout strategies aimed at reducing the influence of external excitation fields. One approach embeds the magnetic field source directly within the chip structure, achieving strong field confinement, improved homogeneity, and lower power consumption, all while remaining compatible with 200 mm wafer‑scale fabrication. Examples will be shown for both dynamic and static detection modes.
