At present, the number of patients with lower extremity dysfunction is increasing year by year. However, traditional rehabilitation training cannot meet the needs of patients for rehabilitation training. Rehabilitation robot is a good solution to train patients instead of the rehabilitation physician. Based on clinical practice experience, a lower limb rehabilitation training system based on virtual reality (VR) is designed, which combined the VR technology and rehabilitation evaluation program to improve the rehabilitation efficiency of patients. According to the functional requirements of the lower limb rehabilitation robot (LLR-RO), the construction of rehabilitation robot control system and sensor system is completed. Based on the Unity3D development environment, a VR scenes of space shooting is planned and created for rehabilitation training VR technology which enables patients to complete the training process while maintaining a pleasant mood. Through the software and hardware debugging, the feasibility, data transmission capability of VR-based remote rehabilitation training system and the synchronization performance of VR scenes and rehabilitation robots are verified. In the future, more virtual reality scenes will be studied to adapt to patients of different genders and ages.

While the low-cost noninvasive measurements of diabetes based on exhalation diagnosis is of high interest, it is still difficult for the needed gas sensors to achieve high sensitivity, low detection limit, and low power consumption. This study presents a highly sensitive acetone gas sensor with ultralow detection limit based on zinc oxide (ZnO)/laser-induced graphene (LIG) composite with heterostructures on interdigitated electrodes prepared by one-step laser direct writing and simple drop casting. The resulting ZnO/LIG-based acetone gas sensor exhibits a large response of −24 % to 1 ppm acetone, a fast response recovery time of 21/23 s, and an ultralow experimentally demonstrated (or theoretical) detection limit of 4 ppb (or 334 ppt). Further combined with a molecular sieve coating layer, the acetone gas sensor can accurately detect acetone in the highly humid environments such as the exhaled breath and differentiate diabetic patients from healthy individuals for early diagnostics and treatment evaluations.
A highly stable and controllable standing micro-bubble formation and manipulation system is reported. The standing air bubbles originate in specially designed crevice structures on microfluidic channel walls in a repe...
