We present a novel method of creating a waterproof wearable fingertip haptic display "AeroFinger" that is very light and small enough to fit on the fingertip and uses no electro-mechanical actuation. The display consists of 4 miniature airbags which are made out of 3D printed Rubber-Like material so that the display size, strength and shape can be customized by the user. A small sized full range speaker is mounted on a closed air chamber where the air is transferred back and forth through a tiny nozzle to the airbag. The Speaker movements creates a difference in air pressure and translated into airbag inflation and deflation. Therefore, AeroFinger can display the low frequency vibrations as force sensation and high frequency vibrations as tactile sensation. Unlike most ungrounded haptic devices which contains electrical components such as motors or vibration actuators, AeroFinger uses no electro-mechanical actuation and thus can be completely submerged on water or could be used in magnetic resonance environments.

『AeroFinger』は3Dプリンターで作成した指先に装着する触感ディバイスです。軽量なこと、また電子部品一切入っていないことが特徴です。そのため、水の中で使用することも可能です。エアーバッグが膨らむことによって指先に圧力やテクスチャーなどの触覚フィードバックを与えます。
1つのデバイスに4つのマイクロエアーバッグが付いており、空気を別々のエアーバッグに出し入れし、三軸の方向情報が提供できます。空気の制御はスピーカーの動きにより実現しています。
