Abstract
Flexible & stretchable bio-medical devices has a lots of advantages including, conformability, Imperceptibility, scar-less contact. Recently, the flexible & stretchable bio-medical devices have been developed to have complicate function by integration of organic electronic circuit and organic functional materials. In integration process, the method of patterning of materials is very important to multiple fabrication. Among the methods of patterning, UV-patterning is easiest way to adapt in fabrication process. To create a UV pattern material, a UV pattern function was applied to a siloxane-based material, allowing it to be used on the substrate and passivation layer of flexible devices. Siloxane based materials can be adjusted their Young’s modulus by choosing species of siloxane network. Thus, the developed UV-patternable Siloxane materials was integrated to bio-medical devices with different purpose, including microneedle with hardness, stretchable substrate with softness. Finally, we demonstrated the integrated bio-medical devices by sensing bio-electrical & chemical elements from animal models.
