제목 Stretchable and Adhesion-Force-Adjustable Reverse-Micelle-Induced Films for Epidermal Devices
초록  The epidermal electronics should have mechanical properties similar to adhesion to the skin. Thus, most skin devices are now very thin. However, this form requires a complicated and expensive manufacturing process and makes the device disposable. Thick forms help overcome these limitations and require greater adhesion, while conventional stretch elastomers are not sticky, but sticky elastomers are less elastic and less durable. To keep it sticky, the molecules in the material should be chains that are joined together very weakly, but this also weakens the material.  
 This study describes the reverse micelle induction process to solve this problem by making a weakly linked region array in a polydimethylsiloxane-based elastomer. The area can be formed and adjusted simply by adding an emulsifier and an inhibitor and has an adhesion (0.014-1.1 N cm-1), a Young's modulus (535-16 kPa) and elongation (430-1340%). In addition, it is excellent in durability (stable up to 10,000 times of stretching), and can be reused and adhered well to human skin.
