Laser-Scribed Soft Bioelectronics and Robotics

Laser-assisted fabrication offers a simple, mask-free, cost-effective approach to pattern conductive materials on various substrates under ambient conditions. This process allows for high-precision customization and miniaturization, essential for emerging soft bioelectronics and robotics applications. With the ability to finely tune the porosity, morphology, composition, and electrical conductivity of the resultant patterns, a broad spectrum of applications can be realized, including biophysical and biochemical sensing technologies, as well as innovations in soft actuators for robotics. In this presentation, I will discuss our latest explorations into laser-scribed graphene and molybdenum dioxide on flexible substrates. I will highlight their significant contributions to the realms of soft bioelectronics and robotics. A showcase of various soft devices we have developed based on these materials will be provided, including sensors for hydration, temperature, electrophysiology, sweat biochemistry, UV, and gas. These demonstrate the material's aptitude in sensory technology. Furthermore, we will display our work in crafting reconfigurable three-dimensional architectures and light-driven smart worms using laser-scribed materials. These instances underscore the immense potential of laser-scribed materials in orchestrating devices with intricate behaviors and responses, paving the way for novel applications in a connected world.
