Implantable bioelectronic devices based on magnetoelectric material

A system comprising:

• a magnetoelectric (ME) component comprising:
• one or more first layers, wherein each of the one or more first layers comprises a piezoelectric material;
• and
• one or more second layers, wherein each of the one or more second layers comprises a magnetostrictive material;
• and
• an energy harvesting circuit comprising a rectifier circuit, wherein the energy harvesting circuit is coupled to the ME component, wherein the energy harvesting circuit includes one or more power point tracking circuits configured to:
• electrically decouple, via a bi-directional converter, the ME component from at least one load configuring a load-independent power at output of the rectifier circuit;
• regulate output voltages for different voltage domains;
• store excess harvested energy from the ME component in a storage element via the bi-directional converter configuring bi-directional transfer of energy to or from the storage element, wherein the storage element is independent from the ME component;
• and
• trigger usage of at least part of the stored excess harvested energy to the at least one load by the bi-directional converter upon detecting that power harvested from the ME component by the energy harvesting circuit is below a threshold.
