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

摘要

A soft sensor using 3D printing according to the present invention is characterized in that two first and second elastic layers having different viscosities are formed and a conductive grease is applied between the first elastic layer and the second elastic layer by 3D printing using a syringe, It is possible to form microchannels of various sizes, numbers and shapes without being restricted by the size or shape of the sensor. In addition, since a mold is not used, a soft sensor having a thinner thickness than that of a mold can be manufactured. In addition, since the conductive grease is 3D-printed using a syringe, the thickness of the microchannel can be minimized. Further, the microchannel formed between the first stretchable layer and the second stretchable layer is formed of conductive grease and maintains the state of gel or sol, so that the stretchability of the microchannel can be secured. Further, since the channel pattern is designed using the CAD / CAM, the channel pattern can be easily designed and modified.
