“…Recent advances in multiferroic magnetoelectric composites 1 have brought us closer to applying fundamental research discoveries to a broad range of applications, including datastorage devices [2][3][4] , probabilistic computing platforms 5 , voltage-tunable radio-frequency microwave devices 6,7 , artificial neural networks 8,9 , and microfluidic particle and cell sorting platforms [10][11][12] . For multiferroic heterostructures, understanding the strain that is coupled into the magnetoelastic structures is necessary, especially any variation in strain with length scales similar to the magnetic element size.…”

We investigate localized in-plane strains on the microscale, induced by arrays of biased surface electrodes patterned on piezoelectrics. Particular focus is given to the influence that adjacent electrode pairs have on one another to study the impact of densely packed electrode arrays. We present a series of X-ray microdiffraction studies to reveal the spatially-resolved micron-scale strain distribution. The strain maps with micron-scale resolution highlight how the local strain

Programmable multiferroic materials can enable a technological transformation in magnetic cell separation, from bulk cell separation via coarsely applied external magnetic fields [1][2][3] Programming magnetic fields with microscale control can enable automation at the scale of single cells ≈10 µm. Most magnetic materials provide a consistent magnetic field over time but the direction or field strength at the microscale is not easily modulated. However, magnetostrictive materials, when coupled with ferroelectric material (i.e., strain-mediated multiferroics), can undergo magnetization reorientation due to voltage-induced strain, promising refined control of magnetization at the micrometer-scale. This work demonstrates the largest single-domain microstructures (20 µm) of Terfenol-D (Tb 0.3 Dy 0.7 Fe 1.92 ), a material that has the highest magnetostrictive strain of any known soft magnetoelastic material. These Terfenol-D microstructures enable controlled localization of magnetic beads with sub-micrometer precision. Magnetically labeled cells are captured by the field gradients generated from the single-domain microstructures without an external magnetic field. The magnetic state on these microstructures is switched through voltage-induced strain, as a result of the strain-mediated converse magnetoelectric effect, to release individual cells using a multiferroic approach. These electronically addressable micromagnets pave the way for parallelized multiferroics-based single-cell sorting under digital control for biotechnology applications.
