Abstract
A hand-wearable device includes an elastic sheet including a first elastic layer and a second elastic layer facing each other; a sensor unit formed by printing a predetermined conductive liquid metal between the first elastic layer and the second elastic layer; a wire unit extending from the sensor unit and electrically connected to the sensor unit; an electrode substrate formed on one side of the wire unit and spaced apart from the wire unit by a predetermined distance; and a connection electrode formed by printing a predetermined conductive liquid metal between the wire unit and the electrode substrate.
Claims20
A hand-wearable device comprising:
- an elastic sheet comprising a first elastic layer and a second elastic layer facing each other;
- a sensor unit formed by printing a predetermined conductive liquid metal between the first elastic layer and the second elastic layer;
- a wire unit extending from the sensor unit and electrically connected to the sensor unit;
- an electrode substrate formed on one side of the wire unit and spaced apart from the wire unit by a predetermined distance;
- and
- a connection electrode formed by printing a predetermined conductive liquid metal between the wire unit and the electrode substrate.
A method of manufacturing a hand-wearable device, the method comprising:
- forming a first elastic layer on a base substrate;
- forming a sensor unit and a wire unit by printing a predetermined conductive liquid metal on the first elastic layer in a predetermined pattern;
- arranging an electrode substrate on one side of the wire unit to be spaced apart from the wire unit by a predetermined degree;
- forming a connection electrode connecting the electrode substrate to the wire unit by printing a predetermined conductive liquid metal on the first elastic layer;
- and
- forming a second elastic layer on the first elastic layer;
- wherein the forming of the connection electrode comprises
- printing the conductive liquid metal from one end of the wire unit while a nozzle is moved in a first direction to a certain extent;
- making the conductive liquid metal erect in a second direction while a nozzle is moved in the second direction to a certain extent;
- moving the nozzle toward the electrode substrate such that the conductive liquid metal electrically contacts one end of the electrode substrate while the conductive liquid metal connected to the nozzle is seated on the electrode substrate;
- and
- separating the conductive liquid metal from the nozzle.
