Electrical Stimulation Promotes Saliva Secretion: Proposition of Novel Interaction via Saliva Secretion

This paper proposes a novel interaction via electrically stimulating the salivary glands. The salivary glands are one of the human effector organs along with the muscles and secretion glands. A method of inducing and/or promoting saliva secretion would benefit eating, drinking, and speaking experience and emotion. Hence, this paper firstly reviews previous studies and the limitations of the conventional technologies, secondly reports our novel percutaneous electrical stimulation method to promote saliva secretion, and thirdly discusses the potential contribution of saliva secretion promoting technologies to the interaction, psychology, and health areas.
