Special Issue Information

Dear Colleagues,

Over the past decade, microrobots have demonstrated their potential to revolutionize traditional medical procedures and medicines in many aspects. The development manipulation technologies and wireless control methodologies of these untethered microrobot/micro-devices will enable minimal invasion into current diagnostic and therapeutic procedures, as well as the possibility of a new procedure that was never before possible. Studies conducted in laboratories on micromanipulation, diagnosis, and microsurgery need to be characterized and verified in clinical settings. On the other hand, robotics have become a part of human life and especially in medical treatment on a global scale, expanding from industrial services to society daily needs. The ultra-high position's accuracy, comparable cost, and scalable capability make robotics ideal for micromanipulation, micro-diagnosis, and microsurgery.

This Special Issue is dedicated to recent advances in research and development within the field of manipulation, diagnosis, and surgery using microrobots in the clinical aspect. We are seeking contributions describing recent advancements in the combination of robotic systems and microrobots that enhance the outcomes of micromanipulation, diagnosis, and microsurgery and enable new procedures.

The ultrasonic actuator can be used in medical applications because it is label-free, biocompatible, and has a demonstrated history of safe operation. Therefore, there is an increasing interest in using an ultrasonic actuator in the non-contact manipulation of micromachines in various materials and sizes for therapeutic applications. This research aims to design, fabricate, and characterize a single-sided transducer array with 56 channels operating at 500 kHz, which provide benefits in the penetration of tissue. The fabricated transducer is calibrated using a phase reference calibration method to reduce position misalignment and phase discrepancies caused by acoustic interaction. The acoustic fields generated by the transducer array are measured in a 300 mm × 300 mm × 300 mm container filled with de-ionized water. A hydrophone is used to measure the far field in each transducer array element, and the 3D holographic pattern is analyzed based on the scanned acoustic pressure fields. Next, the phase reference calibration is applied to each transducer in the ultrasonic actuator. As a result, the homogeneity of the acoustic pressure fields surrounding the foci area is improved, and the maximum pressure is also increased in the twin trap. Finally, we demonstrate the capability to trap and manipulate micromachines with acoustic power by generating a twin trap using both optical camera and ultrasound imaging systems in a water medium. This work not only provides a comprehensive study on acoustic actuators but also inspires the next generation to use acoustics in medical applications. Full article

This paper presents a novel tattooing capsule endoscope (TCE) for delivering a certain amount of ink to the submucosal layer of digestive tract organs. A dual-function permanent magnet is used for locomotion and injection activation. The developed capsule endoscope can move actively in 5 DOF due to the interaction between the permanent magnet and a controllable external magnetic field produced by an electromagnet actuation system. In addition, the permanent magnet is involved in a specially designed mechanism to activate a process that creates a squeezing motion to eject the liquid from the storage room to the target. The dimension of the prototype is 12.5 mm in diameter and 34.6 mm in length. The proposed TCE is tested ex vivo using a fresh porcine small-intestine segment. We were able to direct the TCE to the target and deliver the tattoo agent into the tissue. The proposed mechanism can be used for drug delivery or lesion tattooing, as well as to accelerate the realization of the functional capsule endoscope in practice. Full article
