“…This paper considers two case studies based on endoscopic capsules: the first study uses the robotic capsule endoscopy described by [68] and [81]. This example has no autonomy, but is basically a remotely controlled robot in which all interpretation of (visual) information, and decisions to halt progress or dispense medication are solely at the discretion of the medical practitioner.…”

This paper explores the design process of robotics and autonomous systems using a co-design approach, applied ethics, and values-driven methods. Specifically, the approach seeks to move beyond traditional risk assessment toward a greater consideration of end-user exposure. The goal of the ethics-based co-design approach is to identify end-user and stakeholder values that guide the minimization of end-user vulnerability associated with the employment of autonomous systems. This design process is also used to identify positive consequences that probably increase human wellbeing as opposed to simply avoiding harm. We argue that biomedical autonomous systems design, during the preclinical phase, should bring together diverse stakeholders that would not traditionally be involved in design. We also argue that embedding ethical considerations in the engineering design process should bring together a diverse range of stakeholders to more accurately appreciate possible end-user implications of a design. With complex systems design, such as biotechnologies, greater awareness is necessary of the ethical implications of designed autonomy to end-user exposure.

“…The bionic actuators based on magnetoresponsive composite elastomers have attracted increasing attention due to the excellent deformability and magnetic responsiveness of magnetoresponsive composite elastomers. The magnetoresponsive bionic actuators can clamp a target, overcome obstacles and finally deliver them to destination [7,8] , providing new possibilities to develop smart devices in the promising fields of biomedicine [9][10][11][12][13] , artificial soft robotics [14][15][16] , microfluidic systems [17,18] , flexible electronics [19] , etc.…”

The ability of natural living organisms, transferring deformations into locomotion, has attracted researchers’ increasing attention in building bionic actuators and smart systems. As a typical category of functional materials, magnetoresponsive composite elastomers, comprised of flexible elastomer matrices and rigid magnetic particles, have been playing critical roles in this field of research due to their dynamic changes in response to applied magnetic field direction and intensity. The magnetically driven bionic actuators based on magnetoresponsive composite elastomers have been developed to achieve some specific functions in some special fields. For instance, under the control of the applied magnetic field, the bionic actuators can not only generate time-varying deformation, but also motion in diverse environments, suggesting new possibilities for target gripping and directional transporting especially in the field of artificial soft robots and biological engineering. Therefore, this review comprehensively introduces the component, fabrication, and bionic locomotion application of magnetoresponsive composite elastomers. Moreover, existing challenges and future perspectives are further discussed.

“…Just to name few, today, Wireless Capsule Endoscopy (WCE) is a matter of some discussions. It has made the biggest contribution in the last and current years in scientific domains, not only for troubles diagnostic [8,9], but for biopsy [10] and drug delivery [11,12] purposes as well. This is the field where antennas have played an essential role in one of the promoting medical research fields [13].…”

Wireless capsule endoscopy systems utilize a combination of hardware and software devices to ensure the healthcare of a human being. In praise of involved antennas in the overall medical system design, UWB (Ultra-Wideband) range occupies the highest ranks in the literature. The low-band of UWB is regarded as the best frequency range, within the approved standards, to realize the better transmission of captured medical images by the capsule inside the SI tract, in terms of high resolution and low-path loss. A variety of passive capsules have been designed and made available in the literature, while the accurate design of the corresponding on-body antenna is lagging. For this purpose, this paper provides an extended study of a recently published on-body antenna operating at 3.75-4.25 GHz band. The measured antenna realizes good directivity of 5.78 dBi and 9.50 dBi towards the body without and with the cavity, respectively. The direction of the proposed on-body antenna beam is targeted to be mounted on the body surface. On-body simulations were run with CST Microwave Studio by involving an abdominal multi-layer model, and followed by navel and back areas of the voxel model to predict the antenna behavior close to different lossy body environments. Later, the antenna structure was measured next to a real human abdomen. Simulation results reveal that the proposed antenna with or without the cavity enables enhanced in-body communication when mounted on the abdomen with less path loss. This is supported by the low power totaling 20 dB at the SI (Small Intestine) tract. Furthermore, on-body measurements confirm the good antenna performance. Consequently, the planar compact antenna is regarded as a good on-body candidate for wireless capsule endoscopy systems.
