essence: a breathing jacket

This would be a jacket or shirt that records and plays back breath. Small bladders of air would fill and empty with the breathing pattern, or possibly use another material that expands and contracts with a current flow (some kind of foam?). There could also be an element of heat, as well as sound (either breathing sounds or hearthbeat, like a stethoscope) The recording could come from the last person wearing the jacket, or be sent over the phone. I see this project as an investigation into better incorporating tactility and texture into my tangible media work.
