Abstract

See full text

The present invention is to provide an imperceptible motion sensing device, which includes a non-conductive elastomer made of a pliable and elastic non-conductor (e.g., polyurethane) and having a bumpy side formed with at least one sunken portion thereon, at least one conductive fiber positioned in the at least one sunken portion respectively (e.g., by sewing), and a conductive elastomer made of a pliable and elastic conductor (e.g., a conductive foam or conductive rubber) and provided on the bumpy side of the non-conductive elastomer. When the sensing device is compressed by an external force, corresponding portions of the conductive elastomer and the non-conductive elastomer are compressed and deformed, causing contact and hence electrical connection between the conductive elastomer and the at least one conductive fiber. Thus, the imperceptible motion sensing device not only provides more accurate and more sensitive signal detection, but also ensures consistent performance even after long-term use.
