Abstract

The invention discloses an implanted antenna based on electromyographic signal transmission, which belongs to the technical field of antennas. The implanted antenna comprises a copper foil hollow cylinder, a dielectric substrate, a spiral antenna and a coil, wherein the dielectric substrate wraps the outer side face of the copper foil hollow cylinder, the spiral antenna is wound on the outer side of the dielectric substrate, and the coil is arranged on the outer side of the spiral antenna; the coil feeds in a lumped port mode, and the spiral antenna feeds in a coupled feeding mode. The implanted antenna is small in size, high in efficiency, wide in frequency band and capable of being applied to the human body communication frequency band.

Description

technical field [0001] The invention belongs to the technical field of antennas, in particular to an implanted antenna based on electromyographic signal transmission. Background technique [0002] Human movement is a process in which the brain generates will, the spinal cord generates corresponding patterns of movement, and the fine-grained control of reflex nerves. Compared with the signals collected by physical sensors, bioelectric signals can provide more timely and active feedback on the wearer's motion intentions. When the human body performs upper limb movement, the central pattern generator with the brain as the central nervous system generates the movement initiation intention, and controls the upper limb bones and muscles to perform corresponding actions. Electromyography (EMG) is the temporal and spatial superposition of motor unit action potentials (MUAPs) in numerous muscle fibers. EMG signals reflect the functional state of human neuromuscular activity, are th...
