Direct laser scribed MoO2-based materials and their applications in bioelectronics and soft robotics
Metadata[+] Show full item record
Overcoming the disadvantages of rigid traditional electronic materials, flexible epidermal electronics with soft, elastic and mechanically conformable characteristics are capturing wide attention. In order to meet the requirements of high conductivity of current path and base electrode and good biocompatibility, high sensitivity and stability of monitoring sensor for skin wearable devices, we developed direct laser scribing MoO2 (DLS-MoO2) high conductive trace on breathable, flexible and chemical stability porous SEBS substrate. And by following electrode modifications and functionalization, we fabricated multifunctional flexible sensors including electrophysiological sensors, temperature sensor, UV sensor, humidity sensor, alcohol sensor, and NH3 sensor. Furthermore, photo-actuating soft robotics based on the photothermal transformation of MoO2 have also been developed.
