Printing is an affordable and high-throughput method to process electronics in soft substrates. Printable magnetoresistive pastes have been developed as an alternative single-step fabrication method to obtain magnetic field sensors. Until now, there were no examples of magnetic printed sensors that deliver steady sensing behavior upon mechanical stretching. Here, we will present low-noise printable magnetic field sensors sensitive down to sub-mT, which are mechanically stretchable after printing. The pastes are composites of poly(styrene-butadiene-styrene) copolymer (SBS) with embedded magnetoresistive microflakes. Our printed sensors were demonstrated to be used as electronic skin interfaces.[1]
