Abstract: A method and system for providing electrical stimulation to tissue includes implanting one or more battery-free micro-transponders having spiral antennas into tissue. Energy is provided wirelessly to the plurality of micro-transponders. Tissue is stimulated using the energy.

Abstract: A wireless microtransponder array constructed as a single structure of joined microtransponders. The microtransponders can be configured as a linear array strip with connective material in between. The microtransponders can also be entirely embedded within a strip of material, or joined by a single, common substrate structure.

Abstract: A stimulation system and method includes a stimulation driver which drives bio-interface electrodes with a pulse shape which transmits more than ? of the pulse's total energy before ? of the pulse's total duration has elapsed.

Abstract: A transponder includes a stimulus driver configured to discharge an electrical stimulus when a trigger signal is received. A first conducting electrode is coupled to the stimulus driver and conducts the electrical stimulus discharged by the stimulus driver. A second conducting electrode is coupled to the stimulus driver and conducts the electrical stimulus conducted by the first conducting electrode. A depolarization resistance connects the first conducting electrode to the second conducting electrode in response to the trigger signal.

Abstract: A system of wireless microtransponders, each including a RF resonator circuit for wireless power induction. An external power coil transmits RF energy at a matching or harmonic frequency to deliver power by near field induction to an intermediate, subcutaneous coil. Power is initially transmitted to a subdermal coil and relayed to the subcutaneous coil. The subcutaneous coil is used to transfer the RF signal and power the microtransponder using the resonator circuit. The external power coil RF frequency is tuned to match or be a harmonic of the micro-coil within the resonator.

Abstract: A transponder includes a stimulus driver configured to discharge an electrical stimulus when a trigger signal is received. A first conducting electrode is coupled to the stimulus driver and conducts the electrical stimulus discharged by the stimulus driver. A second conducting electrode is coupled to the stimulus driver and conducts the electrical stimulus conducted by the first conducting electrode. A depolarization switch is gated by the trigger signal and connects the first conducting electrode to the second conducting electrode in response to the trigger signal.

Abstract: A system for interfacing cellular matter with a machine comprising a transponder implantable in cellular matter and configured to detect a first signal. The system also includes a receiver external to the cellular matter and configured to receive a second signal in response to the transponder detection of the first signal. A transmitter is also included in the system to transmit a third signal to a machine in response to the receiver receipt of the second signal.
