Abstract

In this work we present a novel platform of micro-inductors designed to perform magnetic stimulation in neural cells and neural slices in vitro. The fabrication along with design considerations are presented. The fabricated platform consists of a 6×6 array of micro-inductors and achieves spatial magnetic flux profiles with a resolution of 100μm. The capability of the platform to perform magnetic stimulation is explored through finite element method calculations and by testing with a phantom gel, which mimics the electric properties of neural tissue. Biasing the micro-coils with a current of 25mA produces a magnetic flux density with a maximum of 4.28mT above their centre, while the induced electric potential reaches the 233mV in the vicinity of the coils.
