3D Soft sensor using 3D printing and manufacturing method of the same and wearable apparatus having the same

摘要

The soft sensor using 3D printing according to the present invention can form microchannels without being limited in size or shape by 3D printing a conductive liquid metal on the first elastic layer using a syringe. In addition, since a mold is not used, a soft sensor having a thinner thickness can be manufactured than when a mold is used. In addition, since the conductive liquid metal is 3D printed using a syringe, the thickness of the microchannel can be minimized. In addition, the microchannel formed between the first elastic layer and the second elastic layer is formed of a conductive liquid metal, and maintains a liquid state, so that the elasticity of the microchannel can be secured. In addition, since the channel pattern is designed using CAD/CAM, there is an advantage in that it is easy to design and modify the channel pattern.
