“…In the meanwhile, novel flexible structures using elastomers, such as silicone rubber or flexible resin were proposed for artificial muscles [14,[27][28][29][30]. Among them, the bellow is one of the most promising structures, since it can generate a large contraction ratio with a light weight, and it has been widely exploited in soft robotics [14,28,29] that was fabricated by 3D printing [14]. One of the versions (5C-LSOVA) was able to contract up to 51.5 % with 27.66 N blocking force, but a large hysteresis occurred because of the buckling of the thin walls.…”

This paper presents a novel pneumatic artificial muscle (PAM) that is able to generate a high payload and buckling pressure. The proposed actuator exploits open-cell foam, and 0.8 mm thick rigid rings to reinforce structure stiffness, and to implement stable contraction under depressurization. All components are embedded in a sealing elastomeric skin. The actuator can support 6.8 N of external load, which is 34.5 times greater than its own weight (20g). When depressurized, the actuator deforms stably, without buckling. The results of the preliminary experimental analysis show that it is able to contract up to 51.8% upon-80 kPa, with a 5.6% hysteresis for pressure vs. contraction ratio. Moreover, a quasistatic model is proposed to estimate the actuator blocking force, of which the measured maximum value is 32.7 N at-80 kPa vacuum. The presented actuator shows repeatable and reliable performance, providing a promising soft material solution for pneumatic driven movement.

“…Interaction possibilities with inflatables include punching [27], theatrical data display [40], squeezing a mouse [25], exploring affective qualities of simple movements [37], petting inflatable rabbits [14], bodily compression [15], simulating objects in VR [38], force feedback on the arms in VR [19], or a shoulder "tap" to indicate left or right when giving directions [36]. Fabrication techniques include embroidery with silicone bladders [34], silicone bladders [28], stitching on stretchy fabric to control shape change [39], replay direct manipulation [30], firm 3D printed inflatables [20], rapid prototyping [18], and other shape-changing interfaces [24]. These works are often airtight and at relatively smaller scale.…”

This work explores aesthetic, material, and experiential qualities of inflatable architecture. We created large-scale inflatable structuresfrom several stories high, to 15m long, to filling a plaza with an inflatables assemblage-in public space. Working from a first-person approach, we offer somaesthetic, material, and practical reflections and design considerations for architectural inflatables. Our findings detail how such large scale inflatables can alter sensory perception in compelling ways. Our discussion suggests future directions for sensory engagements with architectural inflatables.

“…Emerging technologies make it possible to actuate the curvature [52,63,97] and the softness [20] of UIs. To ensure the efciency of such haptic feedback, HCI designers and researchers need to know users' ability to perceive the curvature of a soft UI.…”

Soft (compliant) curvature-changing UIs provide haptic feedback through changes in softness and curvature. Diferent softness can impact the deformation of UIs when worn and touched, and thus impact the users' perception of the curvature. To investigate how softness impacts users' perception of curvature, we measured participants' curvature perception accuracy and precision in diferent softness conditions. We found that participants perceived the curviest surfaces with similar precision in all diferent softness conditions. Participants lost half the precision of the rigid material when touching the fattest surfaces with the softest material. Participants perceived all curvatures with similar accuracy in all softness conditions. The results of our experiment lay the foundation for soft curvature perception and provide guidelines for the future design of curvature-and softness-changing UIs.
