Abstract: A system for and method of mapping and monitoring posture disclosed. The system includes sensor units that independently collect posture data corresponding to body locations or body positions on subjects and generate posture signals. The posture signals are wirelessly transmitted to one or more computers that are used to process the posture signals and generate posture feedback of the subjects in real-time. The sensor units are preferably accelerometer sensor units. Sensor units are assigned or learn the body locations or body positions, classify body locations or body positions, map and monitor posture, assign posture or activities of subjects and transmit the posture signals to the one or more computers by low-power radio transmitters to provide posture feedback. The system collectively is adaptive for mapping and monitoring posture from body locations or body positions corresponding to spines, arms, legs, necks, heads, thighs, hips, feet and hands of the subjects.

Abstract: A posture monitoring system includes one or more contact sensors that are used to map contact or pressure points of a person's body and produce output signals representative of the person's posture. The contact sensors are embedded within a pad, a cushion, an article of furniture or are integrated into a wearable clothing article. In accordance with the embodiments of the invention, a contact sensor is formed by depositing at least one set of flex sensors on opposite sides of a flexible substrate and electrically coupling the opposed set of flex sensors to provide a voltage bridge that cancels noise and to provide a contact sensor that measures both concave and convex changes in curvature.

Abstract: Ergonomic systems and devices are disclosed. In accordance with the embodiments of the invention, a system or device includes a traction surface that provides traction and/or support through contact with a portion of a user's body. For example, an ergonomic system includes a backrest cushion. The backrest cushion has a traction surface with a plurality of protruding traction pads for resting against a user's back and pulling along the user's back. The traction pads help stretch or decompress the user's spine through contact at multiple positions on the back and flanking the spine. In alternative embodiments of the invention, a chair, resting table, bed or other article of furniture includes one or more traction surfaces that provide traction through contact with one or more corresponding portions of a user's body.
