“…For the remainder of the manuscript, the volumetric flow rate is simply referred as flow rate. It is also able to operate up to 1 Hz, similarly to other examples in literature [18], [12]. In addition, it requires only one control signal, independently from the device's length.…”

“…Among these, DAEs and MAs are able to achieve high frequencies, up to 10 Hz, but the limited stroke is unable to provide high flow rates. Instead, PAMs showcase the best flow rate, from few mL/s up to 75 mL/s, thanks to a modular architecture bioinspired from the small intestine [16], [17], [18]. Although powerful, this solution shows extreme complexity in fabrication, control, and scalability, due…”

Interest in bioinspired peristaltic pumps has grown in popularity among the scientific community in the last decade thanks to their extreme flexibility and their intrinsic compliance. In this paper, we propose a soft peristaltic pump exploiting ballooning. Our aim is to promote and propel forward the ballooned region by controlling the air pressure between the balloon and an external flexible containment tube, to achieve a peristaltic pumping motion with a simple design and using only one control signal. This paper describes the implementation of the pump and the inlet-pump-outlet system, provides an analytical model to predict the pump performance, and showcases experimental results. We also implement a computer simulation to further characterize the device. We show that it is possible to achieve high volumetric flow rates, up to 4.4 mL/s, with only a single control signal, paving the way for more flexible and easy to manufacture peristaltic pumps.

“…There are already a few systems, but these lack simplicity, are not electronic free and prone to failure. Some systems like the soft total artificial heart (Cohrs et al, 2017), the SoGut-artificial stomach peristalsis simulator (Dang et al, 2020), the artificial oesophagus system RoSE (Dirven et al, 2013;Dirven et al 2015;Dirven et al 2017) and the silicon-based peristaltic pump (utilizable as an artificial intestine and oesophagus) (Esser et al, 2019a;Esser et al, 2019b;Tauber and Fitzgerald, 2021) are completely soft but necessitate an external pressure supply (Menciassi and Iacovacci, 2020;Tauber and Fitzgerald, 2021;Hashem et al, 2022). There are a few commercially available artificial hearts, such as the temporary Total Artificial heart (TAH-t) (SynCardia Systems, Inc., Tucson, AZ, United States) and the AESON CARMAT TAH (Carmat, Vélizy-Villacoublay, France).…”

“…Recent developments enable their manufacturing via 3D printing using soft inks or flexible TPU filaments (Wehner et al, 2016;Slesarenko et al, 2018;Skylar-Scott et al, 2019;Conrad et al, 2020;Conrad et al 2021;Conrad et al 2022;Kappel et al, 2022). Most soft robots utilize compliant pneumatic actuators from flexible materials for movement (Whitesides, 2018;Esser et al, 2019a). The pneumatic actuators are mostly outfitted with a strain-limiting layer or thicker walls on one side, creating non-symmetrical conditions leading to directional bending.…”

During the recent decade, we have witnessed an extraordinary flourishing of soft robotics. Rekindled interest in soft robots is partially associated with the advances in manufacturing techniques that enable the fabrication of sophisticated multi-material robotic bodies with dimensions ranging across multiple length scales. In recent manuscripts, a reader might find peculiar-looking soft robots capable of grasping, walking, or swimming. However, the growth in publication numbers does not always reflect the real progress in the field since many manuscripts employ very similar ideas and just tweak soft body geometries. Therefore, we unreservedly agree with the sentiment that future research must move beyond “soft for soft’s sake.” Soft robotics is an undoubtedly fascinating field, but it requires a critical assessment of the limitations and challenges, enabling us to spotlight the areas and directions where soft robots will have the best leverage over their traditional counterparts. In this perspective paper, we discuss the current state of robotic research related to such important aspects as energy autonomy, electronic-free logic, and sustainability. The goal is to critically look at perspectives of soft robotics from two opposite points of view provided by early career researchers and highlight the most promising future direction, that is, in our opinion, the employment of soft robotic technologies for soft bio-inspired artificial organs.

“…In [11] open-source peristaltic pump constructed with a combination of three dimensional (3D)-printed parts and common hardware, which is amenable to deployment with microfluidic devices for point-of-care diagnostics is programmed with the Arduino IDE to generate custom responses to an operator controlled switch. A biomimetic tubular pump actuated by eight silicone-based pneumatic ring actuators with an elliptical inner conduit longitudinal diameter of 2 cm allowing for a simple, quiet and safe transport of a wide variety of Newtonian and non-Newtonian fluids with variable viscosity has been developed in [12]. Combining the peristaltic pumping models with the perspective from passive, capillary e↵ect-driven microfluidics, quasi-1D lumped element model gives a first-order understanding of the working mechanism of discrete actuation pressure pulse-driven peristaltic pumps in discrete flow regime which targets the initial filling process of liquid into microfluidic channels as described in [13].…”

In this article the design and manufacture of the innovative MR rotary brake based on peristaltic pump inspired by the concept model of the pliers and the Rochester Pean forceps are presented . For the calculation and analysis of created structure comprehensive of roller, housing and pliers, simulations concerning the stress and strain are conducted to investigate the deformation and possible failure of part or assembly. Experimental tests including measurements of compression force and magnetic field were conducted to evaluate the performance of proposed designed MR rotary brake based on peristaltic pump system constituted by tube containing MR fluid and pliers with arm responsible of the movement and arm completely hold on bench vise
