Approach

 His main work has focused on developing (i) bio-inspired microrobots and (ii) compact wearable devices both powered by artificial muscles. Regarding bio-inspired microrobots, he explores unknown biological mechanisms from a mechanical engineering perspective. Designing various robots and applying mechanical engneering insights reveal the underlying principles of organisms. His recent work revealed the morphological functions of the ultra-fast deploying structure of Rhagovelia using a bio-inspired robot, the "Rhagobot." 

 In addtion to microrobots, he develops compact wearable devices driven by high-power artifical muscles. Artificial muscles such as shape momory alloys allow the design of comapct and light-weight wearable devices, while still providing powerful acutation. Examples of these compact devices include a high-power and self-sensing haptic glvoe, varifocal AR glasses and a long-term moisture-monitoring wearable device.
