The DEA includes at least one dielectric layer, electrode layers sandwiching the dielectric layer, and a transmitting layer that forms an outermost layer. The at least one dielectric layer includes an expansion-contraction portion, which expands and contracts when applied with a voltage, and a heat generating portion, which generates heat when applied with a voltage. The haptic feedback device is configured to transmit vibration to a user via the transmitting layer by applying an expansion-contraction voltage between the electrode layers sandwiching the expansion-contraction portion through the driving unit, and transmit heat sensation to the user via the transmitting layer by applying a heat generating voltage between the electrode layers sandwiching the heat generating portion through the driving unit."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Haptic feedback device","description":"A haptic feedback device includes a dielectric elastomer actuator (DEA) and a driving unit.
