Flexible & stretchable bioelectronics is a technology that has recently become important, and it is essential research for next-generation wearable devices and implantable devices. Flexible & stretchable biocompatible electronic systems in wearable and implantable electronics, are the most important and basic factor for bioelectronics. Conventional rigid system has limitations of inability to form tissue interfaces due to Young’s modulus mismatch, causing poor device capabilities and noises. To overcome this limitations, flexible and stretchable electronics with low modulus with the same or better performance, such as high selectivity and sensitivity, than existing rigid system is being studied. Unraveling complex neural circuits through various modalities is of great value in identifying neurodegenerative diseases in patients with chronic pain. To provide unprecedented cures for patients, brain signal recording and stimulation such as optogenetics with implantable neural device is essential. Key factors for advancing neuroscience include directions for improving the resolution of brain signal recording or stimulation, and the need for transparency for light stimulation in optogenetics. Climate changes and environmental pollution caused by increases in greenhouse gases and fine dust are serious problems owing to burning the fossil fuels. To solve these problems, research on obtaining renewable energy from natural sources, such as water, wind, and the sun is being actively conducted. Among these sources, solar cells are one of the very promising devices that do not produce carbon and other greenhouse gases while producing electricity. Recently, solar cells manufactured from amorphous silicon, organic materials, and perovskites have been largely studied because of their r
