Data transmission system using a human body as a signal transmission path

Abstract

A data transmission system using a human body as a signal transmission path includes a transmitter and a receiver. The transmitter uses a pair of electrodes which are held in close proximity to the skin of the human body. The transmitter transmits data to the receiver through the signal transmission path partly extending through the human body when a user carrying the transmitter touches a touch electrode of the receiver. The electrodes are integrated into a garment worn by the user in such a manner that the electrodes are kept in a closely facing relation to the skin of the user, thereby establishing the electrical path extending through the human body. With the integration of the two electrodes into the garment, the user wearing the garment as an everyday clothes or uniform can be easy and convenient to carry the transmitter for successful transmission of the data.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] The present patent document is a continuation of U.S. application Ser. No. 09 / 948,638 filed on Sep. 10, 2001, and in turn claims priority to JP 2001-138479 filed on May 9, 2001, the entire contents of each of which are herein incorporated by reference.BACKGROUND ART [0002] 1. Field of the Invention [0003] The present invention relates to a data transmission system using a human body as a signal path, and more particularly to a system composed of a wearable transmitter, a receiver adapted to be connected to an associated equipment which utilize data transmitted from the transmitter, and a garment integrally holding two electrodes for passing the data through the human body. [0004] 2. Description of the Prior Art [0005] U.S. patent application Ser. No. 09 / 605,357 discloses a data transmission system using the human body as a signal path. The system includes a portable transmitter in the form of a wrist watch to be worn on a user, and a si...

AI Technical Summary

Benefits of technology

"The present invention provides a data transmission system that ensures successful data transmission without requiring special attention to the user. The system includes a transmitter that is carried by the user and a receiver that is connected to the user's equipment. The transmitter has a ground electrode and a signal electrode placed close to the user's skin, allowing for an electrical path through the user's body. The system also includes a garment that integrates the electrodes into it, making it easy and convenient for the user to carry the transmitter. The garment can be washed like ordinary clothes, ensuring the system's cleanliness. The system includes a coupling member that makes the case detachable from the garment and the electrical circuitry detachable from the electrodes. The case is water-tight and can be used as a nameplate. These technical features make the data transmission system convenient and comfortable for users."

Problems solved by technology

Thus, the electrodes can be easily integrated into the garment and cannot sacrifice comfortableness of the garment.
