Multi-Body Earpiece

Abstract

The technology provides a multi-body earpiece suitable for use as an in-ear sensor system, which can be used for biometrics or a human-computer interface. The multi-body earpiece includes two body elements connected together by a flexure. These components provide at least 3 points of contact along different parts of the outer ear, in which the flexure is tethered to the two bodies and arranged to lock them in place during wear. In addition to having stability from moving while minimizing sound occlusion, this arrangement enables any electrodes for the on-board sensor(s) to remain in contact with the skin of the ear, and provide as many contact points in desired areas as the electronics dictate for the signals of interest.

Description

BACKGROUND[0001]Wearable sensors have been used to detect bio signals, such as electroencephalogram (EEG) signals, from the wearer's body. These signals can be used for medical or non-medical (e.g., brain control interface) purposes. In the past, caps have been worn on the user's head to capture EEG signals. These caps can capture input via multiple data channels. However, wearing a cap for an extended period of time can be cumbersome and uncomfortable. It can also be difficult to obtain high quality signals, especially if the wearer has thick hair. In-ear sensors, for instance using custom-molded earpieces, have also been considered. Unfortunately, even a custom in-ear sensor assembly may have various drawbacks, including difficulty providing a stable arrangement that is both securely and comfortably maintained in the ear. Other issues can include partially or completely blocking ambient sounds, as well as costly and labor-intensive manufacturing techniques.BRIEF SUMMARY[0002]The t...

AI Technical Summary

Benefits of technology

[0003]Such an arrangement minimizes the amount of material required for the sensor system, while providing a secure-fitting device that can be worn for hours, days or longer in order to provide maximal benefit to the wearer. The arrangement is able to minimize the occlusion of ambient sound so the wearer can easily hear what is going on around him or her, while being comfortable and as unobtrusive as possible.
