Recent years have witnessed unprecedented advances in medical device industry. New technologies, such as 3D printing, organ-on-a-chip, and surgical robots, have emerged and iterated constantly. Innovation is the cornerstone in the development of medicine. Though we still need robust clinical data to evaluate the safety and effectiveness of these new technologies, we never stop our pursuit of more effective technologies and devices with a cautious attitude. With these intentions, we are pleased to introduce this new quarterly journal, Progress in Medical Devices.
