Inkjet-printed proximity sensor for human–robot interaction

With the rapid development of artificial intelligence (AI), the human–robot interaction (HRI) has been attracted considerable attention in recent years. The essential component for high-efficient and high-precision HRI is the sensors that help the humanoid robot to identify and recognize the behaviors of human beings. Traditional sensors such as lidar, sonar, and inertial sensors, are commonly used for the object detection in unseparated environments, very few studies have explored in separate conditions, and therefore, few proximity sensors have been applied on the HRI. Inkjet printing as an emerging technology has wide applications in modern industrial and scientific research field. In this paper, the inkjet-printed proximity sensor is proposed for the HRI. The experimental results show that the proposed sensor has the outstanding performance for the human perception and human tracking.
