Magnetic nanoparticle (MNP) guidance has attracted considerable attention for biomedical applications, such as targeted drug delivery and minimally invasive therapy. However, precise navigation in vivo remains challenging, particularly in high-flow vascular environments, where drag forces dominate p…
An overground track-walking scheme with a body-weight support system can provide task-oriented and repetitive training. Furthermore, it improves gait stability and endurance more effectively than the conventional treadmill walking method. However, it does not improve asymmetry and reduces gait speed
The cable-driven redundant manipulator (CDRM) has significant potential for applications in narrow and hazardous spaces. However, traditional CDRMs have limited stiffness and load capacity due to their cable routing method. To address these limitations, several scholars have proposed new mechanisms…
To effectively enhance the spatial sensation for an immersive user experience (UX) in virtual reality (VR), the locomotion interface (LI) is one of the most critical factors. To offer a room-scale LI suitable for use in typical office or home environments, it is imperative that the LI device enables…
Magnetic Particle Imaging (MPI)-based navigation shows significant potential for accurately guiding microrobots to desired target locations. Existing MPI-based navigation systems have been limited to two-dimensional planar movements due to increased computational load and a lack of efficient 3D actu
Permanent magnetic marker (PMM) has the potential to broaden the scope of medical robots by facilitating the localization of target points even in environments where vision-based methods cannot operate. However, conventional approaches rely on the accuracy of the modeling equations and are not adapt
Cable driven redundant manipulator (CDRM) can provide complex movements with high dexterity and singularity reduction. However, traditional CDRMs with universal joints have the disadvantages of requiring a high number of motors and having a narrow joint workspace. Furthermore, there is a limitation…
For immersive interaction in a virtual reality (VR) environment, an omnidirectional treadmill (ODT) can support performance of various locomotive motions (curved walk, side walk, moving with shooting stance) in any direction. When a user performs lateral locomotive motions on an ODT, a control schem…
Post-stroke gait rehabilitation is necessary to aid social re-integration. An active knee orthosis (AKO) can aid gait training through the provision of bodyweight support and assistive knee torque. However, its use may cause instability and it does not ensure improved gait symmetry and speed. Use of…
Balance problems can be a major cause of falling. Existing gait balance rehabilitation devices usually have limited overground usability due to low portability. Therefore, there is need for development of a portable gait balance rehabilitation system. To fulfill this need, a wearable balance biofeed
Provision of visual feedback under unstable and forcefully perturbed seat conditions can help improve seated balance performance. However, due to visual limitations, some patients may require use of a different modality. Additionally, warning about an upcoming perturbation may improve balance reacti
Magnetically targeted drug delivery (MTD) systems are used in the treatment of various diseases. However, few studies on the targeting of micro-/nano-sized magnetic particles (MPs) inside multi-bifurcations vessel with fluid flow have appeared. Here, we present a user-interface offline programming g
In this paper, a novel, low-cost lower extremity gait rehabilitation device using a single actuator is presented. The proposed device is based on a single DOF 8-bar Jansen mechanism, which was recently introduced as an efficient walking mechanism for legged robots. The mechanism is synthesized to ge…
The control problem in self-adjustable treadmills is to keep the position of the user at a reference position. The position error is the key obstacle in facilitating the abrupt stopping on self-adjustable treadmills. Another difficulty in this application is the oscillatory response of the closed-lo…
The magnetic nanoparticles (MNPs) have been emerging as effective drug carriers. The electromagnetic actuated systems can steer the MNPs in vascular network for targeted drug delivery (TDD) systems. However, the real-time monitoring of MNPs remained as an open challenge which limits the application…
Targeted drug delivery by using magnetic nanoparticles (MNPs) is an efficient technique to deliver drug molecules towards specific tissues in a human body. The MNPs' 1D guidance system is a combined electromagnetic actuation (EMA) and monitoring system, which can provide an accurate control scheme w…
Among most existing gait rehabilitation robots, it is difficult to find adequate devices for gait rehabilitation of chronic stroke patients who can already stand and move but still need to rehabilitate the affected lower limb through simple, compact, and easy-to use devices. This paper presents a no…
Magnetic drug targeting is an approach to guide and concentrate magnetic nanoparticles (MNPs) into the diseased target organ after being injected into blood vessels. Although many works for drug targeting have been conducted, there are few studies on delivering the nanoparticles to the target region…
