Advanced wireless technology in multimedia devices that is used widely in daily life can be applied to medical devices, such as spinal cord stimulator (SCS), for functioning as a multimedia node. This paper describes a SCS prototype that functions as a sensor and actuator for scientific research and potential clinical applications. The SCS is able to generate voltage/current outputs in 4 channels (with 16 electrodes selection) and has the capacity to sense tissue impedance in real-time. Furthermore, the SCS allows for wireless communication with high power efficiency at a long range (up to 2 m). Benefiting from its novel designs for high power efficiency and wireless signal/power transmission, the SCS also satisfies the long-term animal/clinical test requirements for maintaining multimedia link. Our experiments also indicate that the SCS has better performance, such as in electrical parameters and versatility, to relevant studies.
