Systems, articles and methods for wearable electronic devices employing contact sensors

Abstract

Wearable electronic devices that employ one or more contact sensors (e.g., capacitive sensors and / or biometric sensors) are described. Contact sensors include electromyography sensors and / or capacitive touch sensors. Capacitive touch sensors include single-frequency capacitive touch sensors, recently-proposed swept frequency capacitive touch sensors, and a generalized version of swept frequency capacitive touch sensors referred to as multi-frequency capacitive touch sensors. The contact sensors are integrated into various devices, including generic watchstraps that may be substituted for the existing watchstrap in any wristwatch design, generic watch back-plates that may be substituted for the existing back-plate in any wristwatch design, and wearable electromyography devices that provide gesture-based control in a human-electronics interface.

BACKGROUND

[0001] 1. Technical Field

[0002] The present systems, articles and methods generally relate to wearable electronic devices having on-board sensors, and particularly relate to wearable electronic devices that incorporate one or more contact sensor(s) of any one or more of a variety of different types.

[0003] 2. Description of the Related ArtWearable Electronic Devices

[0004] Electronic devices are commonplace throughout most of the world today. Advancements in integrated circuit technology have enabled the development of electronic devices that are sufficiently small and lightweight to be carried by the user. Such “portable” electronic devices may include on-board power supplies (such as batteries or other power storage systems) and may be designed to operate without any wire-connections to other electronic systems; however, a small and lightweight electronic device may still be considered portable even if it includes a wire-connection to another electronic system. For example, a ...
