▎ 摘 要
NOVELTY - An input interface device includes a controller, a plurality of keys, a first grapheme layer and a second grapheme layer. Each key includes an insulation layer, a grapheme aerogel layer, a pressure sensor, a first electrode and a second electrode. The grapheme aerogel layer is disposed below the insulation layer, and is used to store an ionized carrier. The pressure sensor is disposed below the grapheme aerogel layer and coupled to the controller, and is used to detect a press. The first electrode receives a plurality of first charges from the ionized carrier, and the second electrode receives a plurality of second charges from the ionized carrier. The first charges and the second charges are opposite in polarity. The first grapheme layer is coupled to the first electrode of each key and is used to store the first charges. The second grapheme layer is coupled to the second electrode of each key and is used to store the second charges.
