To assist people in practicing mindful breathing and regulate their perceived workload while not disturbing the ongoing foreground task during daily routines, we developed a mobile and personalizable pneumatic-haptic feedback device that provides programmable subtle tactile feedback. The device consists of three soft inflatable actuators embedded with DIY stretchable sensors. We introduce their simple and cost-effective fabrication method. We conducted a technical and user-based evaluation of the device. The user-based evaluation focused on the personalization of the tactile feedback based on users' experience assessed during three pilot studies. Different personalization parameters have been tested, such as two tactile patterns, different levels of intensity and frequency. We collected the participants' self-reports and physiological data. Our results show that the device has the potential of a breathing guide under certain conditions. We provide the main findings and design insights from each study and suggest recommendations for developing an on-body personalizable pneumatic-haptic feedback interface.

“…While vibration feedback can be harder to follow than other types of feedback and is by some perceived as interruptive [28], it may also result in a greater subjective relaxation and decrease in breathing rate compared to, e.g., auditory feedback [9]. However, other forms of immediate haptic feedback on the torso have so far rarely been explored with the exception of a recent study by Foo et al [26]. They noted that rhythmic pulsing compression applied on the torso showed potential to improve focused attention on breathing and adopt a slow breathing rhythm, making it an interesting option for further exploration.…”

So far, DTP is relatively unexplored in interaction design research (with some notable exceptions [18,22,26,27]).

Deep Pressure Therapy relies on exerting frm touch to help individuals with sensory sensitivity. We performed frst-person explorations of deep pressure enabled by shape-changing actuation driven by breathing sensing. This revealed a novel design space with rich, evocative, aesthetically interesting interactions that can help increase breathing awareness and appreciation through: (1) applying symmetrical as well as asymmetrical pressure on the torso;(2) using pressure to direct attention to muscles or bone structure involved in diferent breathing patterns; (3) apply synchronous as well as asynchronous feedback following or opposing the user's breathing rhythm through applying rhythmic pressure. Taken together these explorations led us to design (4) breathing correspondence interactions -a balance point right between leading and following users' breathing patterns by frst applying deep pressure -almost to the point of being unpleasant -and then releasing in rhythmic fow.

“…In addition, peristaltic pumps have a modular design, which allows rapid construction, easy repair, and customization. These properties make soft peristaltic pumps not only appropriate for robotic actuation but also desirable for food handling, wearable haptic devices, compression suits, drug delivery, blood transfer, and implantable pumps, where form factor, compliance, and biocompatibility are critical factors (37)(38)(39)(40)(41).…”

Fluid-driven robotic systems typically use bulky and rigid power supplies, considerably limiting their mobility and flexibility. Although various forms of low-profile soft pumps have been demonstrated, they either are limited to specific working fluids or generate limited flow rates or pressures, making them ill-suited for widespread robotics applications. In this work, we introduce a class of centimeter-scale soft peristaltic pumps for power and control of fluidic robots. An array of high power density robust dielectric elastomer actuators (DEAs) (each weighing 1.7 grams) were adopted as soft motors, operated in a programmed pattern to produce pressure waves in a fluidic channel. We investigated and optimized the dynamic performance of the pump by analyzing the interaction between the DEAs and the fluidic channel with a fluid-structure interaction finite element model. Our soft pump achieved a maximum blocked pressure of 12.5 kilopascals and a run-out flow rate of 39 milliliters per minute with a response time of less than 0.1 second. The pump can generate bidirectional flow and adjustable pressure through control of drive parameters such as voltage and phase shift. Furthermore, the use of peristalsis makes the pump compatible with various liquids. To illustrate the versatility of the pump, we demonstrate mixing a cocktail, powering custom actuators for haptic devices, and performing closed-loop control of a soft fluidic actuator. This compact soft peristaltic pump opens up possibilities for future on-board power sources for fluid-driven robots in a variety of applications, including food handling, manufacturing, and biomedical therapeutics.
