2012
Conference Papers

Abstract

A wearable device to power implanted sensors by means of an inductive link is presented. The system, having size 69 × 40 mm2, is designed to be embedded into a skin patch and located over the implantation area. The system can transfer up to 15 mW within 6 mm in air. Tested with a 17 mm thick beef sirloin placed between the inductors, the device is able to deliver up to 1.17 mW. Downlink communication with the implanted sensors is performed at 100 kbps by using amplitude modulation. Uplink communication is performed at 66.6 kbps by using load modulation. Long range communication between the system and remote devices is enabled by a bluetooth module. The system is powered by two rechargeable lithium-ion polymer batteries and has an autonomy of 10 h in stand-by mode and about 1.5 h in transmitting mode.

Modulation

In electronics and telecommunications, modulation is the process of varying one or more properties of a periodic waveform, called the carrier signal, with a separate signal called the modulation signal that typically contains information to be transmitted. For example, the modulation signal might be an audio signal representing sound from a microphone, a video signal representing moving images from a video camera, or a digital signal representing a sequence of binary digits, a bitstream from a computer.

Quadrature amplitude modulation

Quadrature amplitude modulation (QAM) is the name of a family of digital modulation methods and a related family of analog modulation methods widely used in modern telecommunications to transmit information. It conveys two analog message signals, or two digital bit streams, by changing (modulating) the amplitudes of two carrier waves, using the amplitude-shift keying (ASK) digital modulation scheme or amplitude modulation (AM) analog modulation scheme.

Brain implant

Brain implants, often referred to as neural implants, are technological devices that connect directly to a biological subject's brain – usually placed on the surface of the brain, or attached to the brain's cortex. A common purpose of modern brain implants and the focus of much current research is establishing a biomedical prosthesis circumventing areas in the brain that have become dysfunctional after a stroke or other head injuries. This includes sensory substitution, e.g., in vision.
