The Robotics Revolution Will Be Soft: Soft Robotics Proliferate-Along with Their Sources of Inspiration.

When soft robotics first emerged, it was defined (as breakthroughs often are) by what it was that its traditional counterparts were not, i.e., soft. A decade in, the nomenclature remains apt. The pliant materials used in soft robotics are often both a defining trait and a source of advantage. Soft robots continue to make headlines with their ability to squeeze, octopus-like, through narrow crevices; change shape; and survive impacts that would crush a traditional rigid robot. They distinguish themselves fro...


Precharged Pneumatic Soft Actuators and Their Applications to Untethered Soft Robots.

The past decade has witnessed tremendous progress in soft robotics. Unlike most pneumatic-based methods, we present a new approach to soft robot design based on precharged pneumatics (PCP). We propose a PCP soft bending actuator, which is actuated by precharged air pressure and retracted by inextensible tendons. By pulling or releasing the tendons, the air pressure in the soft actuator is modulated, and hence, its bending angle. The tendons serve in a way similar to pressure-regulating valves that are used ...

The quest for mechanically and biologically functional soft biomaterials via soft network composites.

Developing multifunctional soft biomaterials capable of addressing all of the requirements of the complex tissue regeneration process is a multifaceted problem. In order to tackle the current challenges, recent research efforts are increasingly being directed towards biomimetic design concepts that can be translated into soft biomaterials via advanced manufacturing technologies. Among those, soft network composites consisting of a continuous hydrogel matrix and a reinforcing fibrous network closely resemble...


Exploiting the Dynamics of Soft Materials for Machine Learning.

Soft materials are increasingly utilized for various purposes in many engineering applications. These materials have been shown to perform a number of functions that were previously difficult to implement using rigid materials. Here, we argue that the diverse dynamics generated by actuating soft materials can be effectively used for machine learning purposes. This is demonstrated using a soft silicone arm through a technique of multiplexing, which enables the rich transient dynamics of the soft materials to...

Infinite Set of Soft Theorems in Gauge-Gravity Theories as Ward-Takahashi Identities.

We show that the soft photon, gluon, and graviton theorems can be understood as the Ward-Takahashi identities of large gauge transformation, i.e., diffeomorphism that does not fall off at spatial infinity. We found infinitely many new identities which constrain the higher order soft behavior of the gauge bosons and gravitons in scattering amplitudes of gauge and gravity theories. Diagrammatic representations of these soft theorems are presented.

Vector Effective Field Theories from Soft Limits.

We present a bottom-up construction of vector effective field theories using the infrared structure of scattering amplitudes. Our results employ two distinct probes of soft kinematics: multiple soft limits and single soft limits after dimensional reduction applicable in four and general dimensions, respectively. Both approaches uniquely specify the Born-Infeld (BI) model as the only theory of vectors completely fixed by certain infrared conditions which generalize the Adler zero for pions. These soft proper...

3D patient-specific numerical modeling of the soft palate considering adhesion from the tongue.

Collapse of the soft palate in the upper airway contributes to obstructive sleeping apnea (OSA). In this study, we investigate the influence of the adhesion from the tongue on the soft palate global response. This is achieved using a cohesive zone finite element approach. A traction-separation law is determined to describe the adhesion effect from the surface tension of the lining liquid between the soft palate and the tongue. According to pull-off experimental tests of human lining liquid from the oral sur...

Soft freezing-induced self-assembly of silk fibroin for tunable gelation.

Silk fibroin (SF) hydrogel is a promising candidate in biomaterial field; however its application is quite limited by long-gelation time. In the present study, we developed a novel strategy named soft freezing to accelerate the process and control the sol-gel transition of SF protein. SF protein was induced to self-assembly by soft freezing process for achieving the reconstructed SF solution with metastable structure. It was found that the soft freezing process triggers the structural transition of mainly S...

Modulation of acoustomechanical instability and bifurcation behavior of soft materials.

We demonstrate acoustically triggered giant deformation of soft materials, and reveal the snap-through instability and bifurcation behavior of soft materials in nonlinear deformation regime in response to combined loading of mechanical and acoustic radiation forces. Our theoretical results suggest that acoustomechanical instability and bifurcation can be readily modulated by varying either the mechanical or acoustic force. This modulation functionality arises from the sensitivity of acoustic wave propagatio...

Laser Cutting as a Rapid Method for Fabricating Thin Soft Pneumatic Actuators and Robots.

Pneumatically actuated soft robots address many challenges with interfacing with delicate objects, but these actuators/robots are still bulky and require many hours to fabricate, limiting their widespread use. This article reports a novel design and manufacturing method for ultrathin soft robots and actuators (∼70 μm) using a laser-cutting machine that cuts/welds sheets of thermoplastic polyurethane (TPU) from a 2D CAD drawing. Using this method, five different soft actuators (e.g., bending, rotating, ...

Surgical Technique: Achieving Anatomic Alignment With Temporizing, Ankle-Spanning External Fixation.

Severe injuries to the ankle frequently result in soft tissue trauma too severe to proceed with immediate definitive fixation. Additionally, patients with multiple or vascular injuries may need a temporizing measure before undergoing definitive treatment. Temporizing, ankle-spanning external fixation offers a management strategy that allows for soft tissue rest and prioritized treatment of patients with polytrauma.

Alveolar Soft-Part Sarcoma of the Tongue.

Alveolar soft-part sarcoma is a rare neoplasm of unknown histogenesis that accounts for less than 1% of all soft-tissue sarcomas. The tumor is highly vascularized with small vascular spaces separating nests of cells, and from cytogenetic point of view, is characterized by chromosome rearrangement der(17)t(X:17)(p11:q25) that results in the ASPL-TFE3 translocation. It can occur at any age, but it is most common between 15 and 35 years of age. The prognosis is poor, despite the relatively slow growth of the t...

A Magnetically Controlled Soft Microrobot Steering a Guidewire in a Three-Dimensional Phantom Vascular Network.

Magnetically actuated soft robots may improve the treatment of disseminated intravascular coagulation. Significant progress has been made in the development of soft robotic systems that steer catheters. A more challenging task, however, is the development of systems that steer sub-millimeter-diameter guidewires during intravascular treatments; a novel microrobotic approach is required for steering. In this article, we develop a novel, magnetically actuated, soft microrobotic system, increasing the steerabil...

Topical Issue on Advances in Computational Methods for Soft Matter Systems.

Diagnosis, Prognosis, and Treatment of Alveolar Soft-Part Sarcoma: A Review.

Alveolar soft-part sarcoma (ASPS) is a rare, translocation-driven sarcoma of the soft tissues. Alveolar soft-part sarcoma often affects young adults and is characterized by indolent behavior but early evidence of metastatic spread. After recognition of ASPS as a specific entity in 1952, retrospective data indicated prolonged survival in patients with metastases, despite inherent resistance to conventional doxorubicin-based chemotherapy. Tyrosine kinase inhibitors and immune checkpoint inhibitors have provid...

Influence of soft tissue grafting, orofacial implant position, and angulation on facial hard and soft tissue thickness at immediately inserted and provisionalized implants in the anterior maxilla.

Resorption of hard and soft tissues following immediate implant insertion is frequently reported. Data regarding the influencing factors on facial tissue thickness are rare.

Their structures were elucidated on the basis of extensive spectroscopic analysis, including one and two-dimensional NMR, MS, IR, UV, ...

Soft Robotic Manipulation and Locomotion with a 3D Printed Electroactive Hydrogel.

Electroactive hydrogels (EAH) which exhibit large deformation in response to an electric field have received great attention as a potential actuating material for soft robots and artificial muscle. However, their application has been limited due to the use of traditional two-dimensional (2D) fabrication methods. Here we present soft robotic manipulation and locomotion with 3D printed EAH micro-structures. Through 3D design and precise dimensional control enabled by a digital light processing (DLP) based mic...

Tactile Sensing Applied to the Universal Gripper Using Conductive Thermoplastic Elastomer.

There is increasing interest in the use of soft materials in robotic applications ranging from wearable devices to soft grippers. While soft structures provide a number of favorable properties to robotic systems, sensing of large deformable soft structures is still a considerable challenge; sensors must not inhibit the mechanical properties of the soft body, and the potential infinite degree-of-freedom deformations mean that there is an intrinsically limited resolution of the sensing receptors. An approach ...

Sing softly to evoke a response only from a recent intruder.

Low-amplitude soft songs have been described in many birds, but in most species, research has addressed only broadcast songs. Soft songs may have a similar or distinctive structure in comparison to broadcast songs produced in order to defend a territory and attract females. In some species, such soft songs were found to be produced in an aggressive context and were the best predictors of conflict escalation and later physical attack. However, such observations are not consistent across all species studied. ...

Effect of tricyclazole on morphology, virulence and gene expression of Aspergillus aculeatus for management of soft rot disease in peach.

Aspergillus aculeatus (A. aculeatus), a pathogen of peaches, can cause soft rot and lead to economic losses in agricultural production. However, studies on the prevention of soft rot caused by A. aculeatus have rarely been reported. Tricyclazole (TCZ) is a fungicide that has been widely used in disease prevention of various crops but the inhibitory mechanism of TCZ on A. aculeatus is unknown. Our aims were to determine the effects of TCZ on A. aculeatus.

Determining the porous structure for optimal soft-tissue ingrowth: An in vivo histological study.

The success of osseointegrated transcutaneous prostheses depends on a soft-tissue seal forming at the skin-implant interface in order to prevent infection. Current designs include a flange with drilled holes or a subdermal barrier with a porous coating in an attempt to promote soft-tissue attachment. However, the soft-tissue seal is not reliably achieved despite these designs and infection remains a significant problem. This study investigated soft-tissue integration into fully porous titanium alloy structu...

Phthalates in soft glass (a soft transparent PVC plastic sheet used extensively in household and public place in developing countries in recent years): Implication for oral exposure to young children.

It has been several years that a soft transparent polyvinyl chloride (PVC) plastic sheet, commonly known as "soft glass", or "crystal plate" in China and other developing countries, has quietly and gradually found extensive applications. This material has widely replaced cloth and glass as table cover in household and office, and replaced cloth as door drape in public place in China. In this study, the concentration of plasticizer used in soft glass and the migration of the plasticizer from soft glass to ol...
