The internet of medical things (IoMT) is used for the acquisition, processing, transmission, and storage of medical data of patients. The medical information of each patient can be monitored by hospitals, family members, or medical centers, providing real-time data on the health condition of patients. However, the IoMT requires monitoring healthcare devices with features such as being lightweight, having a long lifetime, wearability, flexibility, safe behavior, and a stable electrical performance. For the continuous monitoring of the medical signals of patients, these devices need energy sources with a long lifetime and stable response. For this challenge, conventional batteries have disadvantages due to their limited-service time, considerable weight, and toxic materials. A replacement alternative to conventional batteries can be achieved for piezoelectric and triboelectric nanogenerators. These nanogenerators can convert green energy from various environmental sources (e.g., biomechanical energy, wind, and mechanical vibrations) into electrical energy. Generally, these nanogenerators have simple transduction mechanisms, uncomplicated manufacturing processes, are lightweight, have a long lifetime, and provide high output electrical performance. Thus, the piezoelectric and triboelectric nanogenerators could power future medical devices that monitor and process vital signs of patients. Herein, we review the working principle, materials, fabrication processes, and signal processing components of piezoelectric and triboelectric nanogenerators with potential medical applications. In addition, we discuss the main components and output electrical performance of various nanogenerators applied to the medical sector. Finally, the challenges and perspectives of the design, materials and fabrication process, signal processing, and reliability of nanogenerators are included.

Electroporation (EP) is an effective and widely accepted intracellular delivery method for fundamental research and medical applications. Existing electroporation methods usually require a commercially available EP system or tailormade high-voltage (HV, up to kV) power source and are complicated, expensive, harmful to the cells, and even dangerous to the operators. A triboelectric nanogenerator (TENG) is a highly studied device that can generate HV output with limited charges and ultrahigh internal impedance. Here, we developed a Bulk Electroporation System based on TENG (BEST). To maximize the load voltage of the TENG, a flowing EP unit with a capillary was designed as a resistive load to realize impedance matching. A low conductivity buffer was used to further match and assist cell electroporation. Besides, the electrical model and experiments on cells transfected with the BEST showed that the bulk electric field of the cell medium could reach up to 1 kV/cm, therefore resulting in a nearly 30 times increase of trans-membrane potential, thus largely improving transfection efficiency. Finally, using 40 kDa FITC−dextran, we showed that a delivery efficiency above 50% with a cell viability maintained over 90% can be achieved in HeLa cells. This work demonstrated the potential of TENG in the biomedical field as a naturally safe HV power source. It also provided a simple, alternative, and low-cost solution for EP research and related biomedicine applications.
