Special Issue Information

Dear Colleagues, 

Despite industrial applications where repeatability, high load capacity, and fast motions are essential features, biomedical applications demand a gentle touch, safe interactions, dexterity, and lightness. Soft robotics is an emerging field of research that has gained significant interest among biomedical researchers due to its unique capabilities and performances. This Special Issue on “Soft Robotics in Biomedical Application” seeks original research articles with novel approaches in soft material designs and fabrications, soft actuation technologies, soft sensors, and control of soft robotic platforms and their applications in the biomedical fields, ranging from macroscale rehabilitations to cell microscale manipulations.

A magnetic-controlled flexible continuum robot (MFCR) is a kind of continuum robot with small-size and flexibility that deforms under controlled magnetic fields, which makes MFCRs easy to fit in special sizes and designs and provides them with the ability to feasibly arrive at the desired area through certain blood vessel bifurcation. The magnetic drive method is suitable for the miniaturization of soft continuum robots but shows limitations in realizing high flexibility. To achieve miniaturization and high flexibility, in this work, the deformation schemes of a magnetic-controlled flexible continuum robot (MFCR) are proposed, simulated, and experimentally validated. The proposed MFCR includes a soft steering part made of a silicone elastomer with uniformly dispersed NdFeB powder which has a specific magnetization direction. With the actuation of different magnetic fields, the proposed MFCR shows three different deformation modes (C-shape, J-shape, and S-shape) and high flexibility. By using the potential energy model combined with magnetic and elastic potential energy, the quasi-static deformation model of MFCR is built. Through various simulations and experiments, we analyzed and predicted different deformation modes. The results from the experiments demonstrate the accuracy of the deformation model. The results indicate that the MFCR has good control precision and deformation performance with potential applications in robot-assisted minimally invasive surgery. Full article

This journal review article focuses on the use of assistive and rehabilitative exoskeletons as a new opportunity for individuals with diminished mobility. The article aims to identify gaps and inconsistencies in state-of-the-art assistive and rehabilitative devices, with the overall goal of promoting innovation and improvement in this field. The literature review explores the mechanisms, actuators, and sensing procedures employed in each application, specifically focusing on passive shoulder supports and active soft robotic actuator gloves. Passive shoulder supports are an excellent option for bearing heavy loads, as they enable the load to be evenly distributed across the shoulder joint. This, in turn, reduces stress and strain around the surrounding muscles. On the other hand, the active soft robotic actuator glove is well suited for providing support and assistance by mimicking the characteristics of human muscle. This review reveals that these devices improve the overall standard of living for those who experience various impairments but also encounter limitations requiring redress. Overall, this article serves as a valuable resource for individuals working in the field of assistive and rehabilitative exoskeletons, providing insight into the state of the art and potential areas for improvement.

Title: A Soft Prosthetic Hand for Children with the Ability to Execute Intricate and Skillful Motions
Authors: Hironari Taniguchi 1*, Ren Yakami 1, Kosuke Morinaga 2 and Shuichi Wakimoto 3
Affiliation: Department of Robotics and Design, Osaka Institute of Technology, 2 Department of Rehabilitaion, Hiroshima International University, 3 Department of Systems Engineering, Okayama University
Abstract: We have developed a soft prosthetic hand using thin McKibben artificial muscles. The prosthetic hand can grasp objects of various shapes and has the advantages of durability and high safety for the user and others. We evaluated the performance of the developed prosthetic hand and conducted user tests using only the prosthetic hand. Of the 19 tasks performed, 14 tasks were successfully completed. The user was able to achieve movements comparable to those of normal subjects in the grasping task. The results of the user test indicate that the purpose of assisting bimanual movements in daily life is sufficiently fulfilled.

Title: Elastocaloric effect in shape memory alloys: a review towards biomedical applications
Authors: Girolamo Costanza
Affiliation: Industrial Engineering Department, University of Rome “Tor Vergata”, Via del Politecnico 1, 00133 Rome, Italy
Abstract: This review paper provides an overview of the elastocaloric effect in shape memory alloys (SMA), highlighting the potential of this technology, so far deployed to replace the traditional vapor compression cycle in green cooling systems, for future and innovative applications in the bio-medical sector. After an introduction on SMA’s elastocaloric effect and its relevance for medical and biomedical field, the authors in this work examine the principles and mechanisms at the base of this unique property, with a particular focus on key indices essential to evaluate performances and the differences characterizing most used elastocaloric alloys, also exploring strategies currently in place to improve performances. Thereafter, the discussion will center on the state of the art of elastocaloric device’s design and development. It concludes by analyzing future directions of elastocaloric cooling for biomedical applications, including possible upcoming medical and biomedical devices, evaluating challenges that researchers still need to address for the adoption of elastocaloric property of shape memory alloys in the biomedical field.
