Magnetoelectric data and power to miniature biodevices with tunable amplitude and waveform

A system comprising:

• a magnetoelectric film;
• a magnetic field generator configured to generate a magnetic field at an input frequency between 20-500 kHz, wherein the magnetic field generator is configured to transmit downlink data by performing amplitude shift keying (ASK) modulation of the magnetic field;
• and
• an electrical circuit coupled to the magnetoelectric film, wherein:
• the magnetoelectric film is configured to produce an electrical output signal when the magnetoelectric film is stimulated by the magnetic field at the input frequency;
• the electrical circuit configured to receive the electrical output signal comprises:
• a charging circuit configured to extract power based on the electrical output signal;
• a stimulation driver configured to modify the electrical output signal such that the electrical output signal has an output frequency between 0.5-1000 Hz to stimulate a biological tissue;
• and
• a data circuit configured to recover the downlink data encoded via the amplitude shift keying (ASK) modulation of the magnetic field;
• and
• the electrical circuit is configured to transition between the power, the stimulation and the data recovery based on modulation of the magnetic field.
