We report classes of electronic systems that achieve thicknesses, effective elastic moduli, bending stiffnesses, and areal mass densities matched to the epidermis. Unlike traditional wafer-based technologies, laminating such devices onto skin leads conformal contact adequate adhesion based on van der Waals interactions alone, in a manner is mechanically invisible user. describe incorporating electrophysiological, temperature, strain sensors, as well transistors, light-emitting diodes,...

Materials and designs are presented for electronics sensors that can be conformally robustly integrated onto the surface of skin. A multifunctional device this type record various physiological signals relevant to health wellness. This class technology offers capabilities in biocompatible, non-invasive measurement lie beyond those available with conventional, point-contact electrode interfaces

Abstract Stretchable organic light-emitting devices are becoming increasingly important in the fast-growing fields of wearable displays, biomedical and health-monitoring technology. Although highly stretchable have been demonstrated, their luminous efficiency mechanical stability remain impractical for purposes real-life applications. This is due to significant challenges arising from high strain-induced limitations on structure design device, materials used difficulty controlling...

Owing to restrictions on forming dimensions, laser powder bed fusion (LPBF) components will continue require welding in the future. The post-weld thermal cracking of LPBF-Haynes 230 superalloys has become a key issue hindering their assembly service. In this study, it was found that both continuous TCP phase and M5Si3 silicides near crack have large interface strain with matrix. Replacing C Si atoms B at reduces melting point carbides grain boundaries (GBs), thereby inducing solidification...

The unique cellular structure has been reported to be the dominant reason for remarkable mechanical properties in laser powder-bed fusion (LPBF) superalloys. However, specific strengthening mechanism of needs further researched. In this study, microstructure and tensile a composition-optimized Haynes 230 alloy fabricated by LPBF method were systematically investigated. post-heated HT1 HT2 samples with different grain structures served as reference. results show that micron-scale...
