![]() Various nanocomposite materials blending nanomaterials and elastic polymers have recently attracted attention for such flexible electronics. The development of such construction processes would shift flexible electronics to a new technical paradigm. However, the construction of skin-like electronics on which commercial electronic components can be mounted by a simple and cost-effective process remains challenging. ![]() Most electronic skins were developed through new processes involving innovative design concepts with established materials or by fabricating devices with newly developed stretchable composites. In recent decades, some electronic skin materials have been developed, demonstrating potential applications in wearable electronics, flexible and stretchable circuits, flexible displays and energy storage devices, and electronic skins 1, 2, 3, 4, 5, 6, 7, 8, 9, 10. For such purposes, highly stretchable, flexible, and biocompatible electronics are of great interest. Recent progress in wireless communication, Internet of Things (IoT) devices, and biomedical engineering have enabled continuous monitoring of mental and physical health, which is one of the most important issues for ubiquitous healthcare using mobile devices. This simple and cost-effective fabrication method for CNT/PDMS composites provides a promising process and material for various applications of wearable electronics. ![]() We demonstrate the potential for the healthcare field through strain sensor, flexible electric circuits, and biopotential measurements such as EEG, ECG, and EMG. It is also biocompatible and mechanically stable, as demonstrated by cytotoxicity assays and cyclic strain tests (over 10,000 times). The material provides high flexibility, elasticity, and electrical conductivity without requiring a sandwich structure. After vaporizing the IPA, various shapes and sizes can be easily created with the nanocomposite, depending on the mold. To achieve uniform distributions of CNTs within the polymer, an optimized dispersion process was developed using isopropyl alcohol (IPA) and methyl-terminated PDMS in combination with ultrasonication. We have developed a nanocomposite of carbon nanotubes (CNTs) and polydimethylsiloxane (PDMS) elastomer. However, the construction of flexible and elastic electronics, on which commercial electronic components can be mounted through simple and cost-effective processing, remains challenging. This interest in wearable electronics, stretchable circuits, and flexible displays has created a demand for stable, easily manufactured, and cheap materials. The development of various flexible and stretchable materials has attracted interest for promising applications in biomedical engineering and electronics industries.
