Develop Low Dimensional Materials for Smart Sensing and Minimum Invasive Biomedical Technologies( I )

In recent years, with the advent of wearable sensing devices, the concept of "Smart Healthcare" has gradually emerged. The key to this is the rise of the sensor network. With various kinds of sensing devices, the healthy condition can be instantly detected, and analyzed, reducing the waiting time in traditional medical Procedures. However, the advancement of the sensing device relies on the semiconductor technology. As the dimension of semiconductor material reaches the physical limitation, leading to great challenges for semiconductor industry. Fortunately, the appearance of two-dimensional materials brings new opportunities to next generation sensing components. Nevertheless, with the rapid growth of wearable sensing devices, another critical problem is appropriate power supply. Although conventional batteries can still be applicable, the problems of their rigidity, high pollution, and replacement are unable to solve. In view of this, in recent years, the emergence of nanogenerator technology has activated the new progress of power supply for wearable sensor, which can harvest energy from the environment and convert it into electricity. In this study, we plan to utilize two-dimensional materials not only in piezoelectric nanogenerators, but also integrate into self-powered biomedical sensing systems, which can be further applied to minimum invasive medical technologies. The major topics will be discussed in three aspects. First, we will combine medical robots with 2D materials to explore the feasibility of self-powered sensing systems for robot-assisted surgery. Second, we will explore the biocompatibility of 2D materials and apply 2D material-based piezoelectric nanogenerators to wound care. Finally, we would like to make a further step from wearable medical sensing device to in vivo drug release, the potential and feasibility of two-dimensional materials in ingestible microrobot applications will be investigated.
