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

摘要

According to the present invention, a soft sensor using three dimensional printing uses a syringe to three dimensionally print a conductive liquid metal on a first flexible layer to form a micro channel without being affected by limitations on sizes and shapes. Also, since a mold is not used, a soft sensor thinner than a case where a mold is used can be manufactured. Also, since the syringe is used to three dimensionally print the conductive liquid metal, the thickness of the micro channel can be minimized. Also, since the micro channel formed between the first flexible layer and a second flexible layer is made of the conductive liquid metal to maintain a liquid state, flexibility of the micro channel can be secured. Also, since a channel pattern is designed by using CAD/CAM, the channel pattern can be easily designed and modified.
