Tactile devices are often used in the field of robotics; however, the development of compact high-resolution tactile devices remains challenging. In this study, we developed a haptic device for force presentation using a DC motor and a tactile sensation device to simultaneously present haptic and tactile stimuli. A microelectromechanical system was selected to maintain the compactness of the tactile device. Piezoelectric micromachined ultrasonic transducers are known for high-power stimulation, and we selected lanthanum-doped lead zirconate titanate as the high-power amplified actuator. A finger mount structure that transfers force for amplifying ultrasonic waves was considered to combine acoustic pressure and aeroacoustics by attaching silicone rubber. The device was fabricated, and the performance of the tactile sensations was evaluated. The developed device uses the novel concept of combining acoustic pressure and aeroacoustics, and its compactness renders it suitable for wearable systems.
触觉设备常用于机器人技术领域；然而，开发紧凑的高分辨率触觉设备仍然具有挑战性。在本研究中，我们开发了一种用于力呈现的触觉设备，该设备使用直流电机和触觉传感设备来同时呈现触觉和触感刺激。我们选择了微机电系统来保持触觉设备的紧凑性。压电微机械超声换能器以高功率刺激而闻名，我们选择掺镧锆钛酸铅作为高功率放大致动器。通过连接硅橡胶来结合声压和气动声学，设计了一种用于传递力以放大超声波的手指安装结构。制造了该设备，并对触觉性能进行了评估。所开发的设备采用了结合声压和气动声学的新颖概念，其紧凑性使其适用于可穿戴系统。
