Development of a cost-efficient Braille device is a crucial challenge in the haptic technology to improve integration of visually-impaired people. Exclusion of any group threatens the proper functioning of the society. Commercially available Braille devices still utilize piezo-electric actuators which are expensive and bulky. The challenge of more adapted Braille device lies in the integration of a high number of actuators-of a millimetric scale-in order to move independently a matrix of pins acting as tactile cues. Unfortunately no actuation strategy happens to be adapted to tackle this challenge. In this study, we develop a soft actuator based on a thermosensitive poly(n-isopropylacrylamide) (PNIPAM) gel. We introduce macroporosity to the gel (pores of 10 to 100 µm). It overcome the diffusion-which is the limiting kinetic factor-and accelerate the gel response time from hours for bulk gel to seconds for macroporous gel. We study the properties of porous gels with various porosity. We also compare mechanically reinforced nanocomposite gel (made of PNIPAM and Laponite clay) to "classic" gel. As a result, we develop a fast actuating gel with high cyclic performance. We then develop a single pin Braille setup, where actuation is controlled thanks to a swift temperature control of a macroporous gel cylinder. This new strategy offers a very promising actuation technology. It offers a simple and costefficient alternative to the current Braille devices.
