Systems and techniques for wireless implantable devices, for example implantable biomedical devices employed for biomodulation. Some embodiments include a biomodulation system including a non-implantable assembly including a source for wireless power transfer and a data communications system, an implantable assembly including a power management module configured to continuously generate one or more operating voltage for the implantable assembly using wireless power transfer from the non-implantable assembly, a control module operably connected to at least one communication channel and at least one stimulation output, the control module including a processor unit to process information sensed via the at least one communication channel and, upon determining a condition exists, to generate an output to trigger the generation of a stimulus.

System for wireless recording and stimulating bioelectric events

A wireless power transfer system is disclosed. The system includes a first resonator having a first resonant frequency &#x3c9;, a half power bandwidth &#x394;&#x3c9;, and an unloaded quality factor Qo=&#x3c9;/&#x394;&#x3c9;coupled through a first coupling circuit to a power source, a second resonator having a second resonant frequency &#x3c9;, a half power bandwidth &#x394;&#x3c9;, and an unloaded quality factor Qo=&#x3c9;/&#x394;&#x3c9;coupled through a second coupling circuit to a load, the first resonator disposed a distance away from the second resonator, wherein the distance is smaller than the first and second resonant wavelengths, the first and second coupling circuits are configured so that up to a maximum achievable power transfer efficiency between the first and second resonators can be achieved, wherein Qoand Qocan be less than 100.
