Soft robotics has gone through a decade of tremendous progress in advancing both fundamentals and technologies. It also seen wide range applications such as surgery assistance, handling delicate foods, wearable assistive systems driven by its soft nature that is more human friendly than traditional hard robotics. The rapid growth introduces many challenges, which vary with applications. Common challenges include the availability materials for realizing different functions precision speed...

An open-source precision pressure pump system and control software is presented, primarily designed for the experimental microfluidics community, although others may find additional uses this source. This mechatronic coined 'µPump,' its performance rivals that of commercially available systems, at a fraction cost. The accuracy, stability, resolution are 0.09%, 0.02%, 0.02% full span, respectively. settling time to reach 2 bar from zero stabilize less than s. Material building four-channel...

Residual limb volume fluctuation and the resulting contact pressures are some of key factors leading to skin ulcerations, suboptimal prosthetic functioning, pain, diminishing quality life transtibial amputees. Self-management socket fit is complicated by peripheral neuropathy, reducing perception pressure pain in residual limb. We introduce a novel proof-of-concept for liner with potential dynamically adjust between socket. The core technology small air microfluidic chip (10 cm3 10 g)...

A proof of concept a novel air microfluidics-enabled soft robotic sleeve to enable lymphedema treatment is presented. Compression sleeves represent the current, suboptimal standard care, and stationary pumps assist with lymph drainage; however, effective systems that are truly wearable while performing daily activities very scarce. This problematic trade-off between performance wearability requires new solution, which addressed by an innovative microfluidic device. Its novelty lies in use...

Abstract We present a novel electronics-free soft robotic knee brace which employs closed-loop fluidic regenerative (CLFR) system for dynamic unloading in unicompartmental tibiofemoral osteoarthritis (OA). The existing unloaders are bulky, large, and heavy, have low compliance likely due to the use of an electrical control box, is eliminated CLFR system. consists commercial brace, spring-loaded bellow inserted under heel inside shoe, soft-fluidic actuator (bladder), tubing fluid transfer....

A dynamic and low-profile unloader tibiofemoral knee brace is designed prototyped by synergizing concepts from the fields of microfluidics soft robotics. Microfluidics provides strategies for miniaturization multiplexing while robotics afford tools to create fluidic actuators allow compliant inherently safe robotic assistance as part clothing. The response during gait cycle, where a three-point leverage torque provided only stance phase contribute joint stability when required enhance...

In this paper, we propose a modular soft-rigid hybrid (MSRH) approach for designing highly anthropomorphous and dexterous robotic hand. This MSRH allows the hand to possess an inherently soft compliant interface suitable pHRI while maintaining structural rigidity of robot with usage rigid skeletons. We share details design rationale, fabrication assembly methods, evaluation first prototype. Even though presented prototype is scaled be 125% average human hand, mechanical components only weigh...

Vertical displacement of the residual limb within transtibial prosthetic socket, often known as "pistoning" or downward movement, may lead to skin breakdowns and ulcers. Downward movement is particularly difficult self-manage for diabetic individuals living with amputation because diminished sensation in from peripheral neuropathy. Therefore, a customizable sensor at distal end that can alert users when high-risk pistoning occurs urgently needed.Presented herein first time lightweight,...

Lymphedema patients often turn to at-home static and active compression devices when daily manual lymph drainage performed by a clinician is not possible.These are engineered replicate the administered clinicians push fluid away from extremities prevent further accumulation in limbs reduce swelling.In typical or fabricbased garment, achieved designing circumference of free fabric be smaller than arm on which it worn.As result, garment worn, there simultaneous tension fabric, as well radial...

Open-source droplet microfluidic systems are envisioned to decrease the barriers entry for exploration in new research areas and increase adoptions existing such as micro total analysis systems.At heart of microfluidics is a pneumatic pressure control system, which produces pulseless pressure-driven flow manipulate nanoliter-sized movement environments.Currently, this device remains barrier regarding cost performance.Commercially available off-the-shelf customized offer high performance at...
