Zhenan Bao's recent research has included development of an ultrasensitive, highly flexible, electronic sensor that can feel a touch as light as an alighting fly. Manufactured in large sheets, the sensors could be used in artificial electronic skin for prosthetic limbs, robots, touch-screen displays, automobile safety and a range of medical applications. Research areas in the Bao Group include synthesis of functional organic and polymer materials, organic electronic device design and fabrication, and applications development for organic electronics. Bao's approach is multidisciplinary, involving concepts and expertise from chemistry, chemical engineering, biomedical engineering, materials science and engineering, physics, and electrical engineering. The devices of current interest are organic and carbon nanotube thin film transistors, organic photovoltaic cells, chemical/biological sensors and molecular switches. These devices are used as characterization tools for fundamental charge transport and photophysics studies. They are also of practical interest for nano-scale electronics, alternative energy sources, low cost and large area flexible plastic circuits, displays, and disposable sensors. In 2011, Professor Bao was listed by Thomson Reuters among the world's top 100 materials scientists who achieved the highest citation impact scores for their papers.
