Normalized resistance noise power spectral density (PSD) of a Pt-sensor with dimensions 15.1 μm × 1.3 μm × 0.28 μm taken at room temperature. Inset: Voltage noise PSDs taken at currents I = 38.8 μA (blue) and I = 0 (black). The black curve corresponds to thermal noise, whereas the blue curve can be fitted to S ∝ 1/fα with a slope α = 1.03.
