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.
Claims21
A wireless transponder comprising:
- a stimulus driver configured to output an electrical stimulus;
- first and second conducting electrodes operatively coupled to said stimulus driver and connected to receive the electrical stimulus discharged by said stimulus driver through tissue there between;
- a depolarization switch connecting said first conducting electrode to said second conducting electrode after said stimulus.
The wireless transponder system comprising:
- an external resonator;
- an internal resonator receiving resonant energy from said external resonator;
- a depolarizing driver connected to said internal resonator;
- and
- biocompatible electrodes connected to said depolarizing driver;
- wherein said depolarizing driver provides a voltage between said biocompatible electrodes and subsequently shorts said electrodes.
A depolarizing driver comprising:
- a voltage source;
- a stimulation switch connecting said voltage source to a first biocompatible electrode and a second biocompatible electrode;
- and
- a depolarizing switch connecting said first biocompatible electrode to said second biocompatible electrode at a time relative to the connection of said stimulation switch.
