On September 20th, 2024, Dr. Zhou Li from the Beijing Institute of Nanoenergy and Nanosystems, Chinese Academy of Sciences, delivered a lecture titled "Self-Powered Medical Devices and Electrical Stimulation Therapy" to the faculty and students of the Shenzhen University Medical School. This lecture constituted the 116th talk of the Shenzhen University Medicine Forum, and was held at Shaheyuan on Lihu Campus. The lecture was arranged by Prof. Xueji Zhang from the School of Biomedical Engineering of Shenzhen University Medical School.

Electrical activity regulation has become an important means of treating diseases. Nanogenerators are a novel energy conversion device that can convert low-frequency mechanical energy into electrical energy. These devices have attracted widespread attention due to their diverse structures, flexibility, weavability, and high output voltage. Dr. Zhou Li and his team have conducted in-depth studies in this field and have efficiently converted mechanical energy from human motion into electrical energy via nanogenerators that power electrical stimulation devices and biosensors. In effect, they have created self-powered electronic medical devices and sensors.

Dr. Zhou reported on using heartbeat-generated electricity to power pacemakers and achieving improvements in heart rate and arrhythmia in large animal experiments. He also developed degradable self-powered electrical stimulation devices that regulate neural cell growth, promote osteoblast proliferation, and aid in wound healing. These devices are fully absorbable by the body, demonstrating excellent biocompatibility. Additionally, he introduced the concept of minimally invasive self-powered cardiovascular sensors, which show great potential for clinical applications due to their high level of biocompatibility and low invasiveness.

This lecture deepened the audience's understanding of the cutting-edge technologies underlying self-powered electronic medical devices and electrical stimulation therapies. Dr. Zhou's captivating presentation sparked lively discussions, with faculty and students posing many questions during the Q&A session. Dr. Zhou patiently and thoroughly addressed each question, creating an enthusiastic atmosphere.
