Abstract: A wireless electroencephalogram (EEG) recording system is provided, comprising: one or more two-channel electrodes; an analog-to-digital converter (ADC) configured to capture EEG data detected by the one or more electrodes; a digital controller configured to encode the captured EEG data into a single-bit series, and generate a packet using the single-bit series; and a radio frequency (RF) transmitter configured to transmit the packet to an external receiver. In some examples, the wireless EEG recording system further includes a battery powering the one or more ADCs, the digital controller, and the RF transmitter. For instance, in some examples, the wireless EEG recording system further includes an adhesive patch configured to be attached to the head of a patient, wherein the one or more two-channel electrodes, a chip including the ADC, the digital controller and the RF transmitter, and the battery are each attached to the adhesive patch.

Abstract: Described is a locomotive implant for usage within a predetermined magnetic field. In one embodiment magnetohydrodynamics is used to generate thrust with a plurality of electrodes. In another embodiment, asymmetric drag forces are used to generate thrust.

Abstract: Described herein are methods of making and using and apparatus for wirelessly communicating data and providing power, particularly from a location exterior to a body and to an implantable device disposed within a body with tissue. The described embodiments provide apparatus and methods for efficiently transfer data and power between an external transceiver and an (implanted) biomedical device. The method is to modulate power carrier, which wirelessly powers the device, using an asynchronous modulation scheme, such as amplitude shift keying (ASK) modulation, with minimal modulation depth in order to not disrupt the power flow. The digital data is encoded in the pulse width, eliminating the need for synchronization to the power carrier signal and further minimizing the power consumption necessary for data transfer. Additionally, a reverse backscatter method for obtaining data from the implant is described that has flexible, low power operation.

Abstract: Implantable devices and/or sensors can be wirelessly powered by controlling and propagating electromagnetic waves in a patient's tissue. Such implantable devices/sensors can be implanted at target locations in a patient, to stimulate areas such as the heart, brain, spinal cord, or muscle tissue, and/or to sense biological, physiological, chemical attributes of the blood, tissue, and other patient parameters. The propagating electromagnetic waves can be generated with sub-wavelength structures configured to manipulate evanescent fields outside of tissue to generate the propagating waves inside the tissue. Methods of use are also described.

Abstract: An implantable device is provided that can include any number of features. In some embodiments, the device includes a coil antenna configured to receive wireless power from a power source external to the patient. The device can include at least one sensor configured to sense a bodily parameter of the patient. The device can also include electronics configured to communicate the sensed bodily parameter of to a device located external to the patient. Methods of use are also described.
