Recent Trends in Self-Healing Soft Electronic Materials and Devices

Dr. Tan and researcher introduce recent trends in Self-healing Soft Electronic Materials and Devices. The emergence of smart, functional SHPs will be highly beneficial to the advancement of the next-generation self-healing soft electronic devices. Autonomously self-healing devices could help to minimize the need for repair or replacement of electronics and machines, potentially reducing the cost of materials and reducing electronic waste.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
