Abstract
Systems and methods for a shape-memory in-ear biosensor for polysomnography and monitoring physiological signals are provided. Various embodiments include an earpiece made from a shape memory or temperature-dependent phase transition material embedded into polydimethylsiloxane elastomer body. The earpiece can use electrodes to detect physiological signals by making direct contact with a user's skin and without the use of electrically conductive gel. When heated above the glass transition temperature of the shape memory polymer, various embodiments of the biosensor may be folded. When cooled, the biosensor will maintain the folded shape. The folded biosensor may then be inserted into the ear canal of a user where, in response to heating by the user's body, it partially unfolds to conform to the shape of the ear canal.
