传统的气动触觉显示器需要一个复杂的重量系统，因为空气是通过空气压缩机的管道输送的。为了解决这个问题，我们提出了一种使用液气相变致动器和Peltier装置的触觉显示器。该致动器由含有低沸点液体的薄塑料袋组成。液体的温度由与执行器紧密接触的珀尔帖装置控制。这种方法允许软执行器在不使用压缩机和管道的情况下充气，使我们能够实现小而轻的触觉显示。我们实现了具有10平方毫米小袋的触觉显示器，并评估了它的特性。我们确认最大输出力接近1.5 N，这与现成的可穿戴触觉显示器的水平相似。
Conventional pneumatic haptic displays need a complex and weight system because air is fed through a tube from an air compressor. To address this problem, we propose a haptic display that uses a liquid-to-gas phase change actuator and Peltier device. The actuator is composed of a thin plastic pouch containing a low boiling point liquid. The temperature of the liquid is controlled by a Peltier device in close contact with an actuator. This approach allows soft actuators to be inflated without the use of a compressor and tubes, allowing us to realize a small and light haptic display. We implemented the haptic display that has a pouch of 10 mm square and evaluated the characteristics of it. We confirmed that the maximum output force reached almost 1.5 N, which is a similar level to off-the-shelf wearable haptic display.
