Abstract
A unipolar living tissue stimulator of the implantable type with an outer plate electrode which in one embodiment consists of a flat metal plate slotted by slots to form a plurality of electrically conductive strips. Each strip is electrically in contact with any other strip through only a single path. The strips are dimensioned so that any substantially square or circular surface area on any strip is significantly smaller than the total conductive surface area of the plate. Consequently, the heating of the slotted plate due to an external alternating magnetic field is reduced significantly.
