A new tactile device using magneto-rheological sponge cells for medical applications: Experimental investigation

Over the past few decades, tactile sensors have become an emerging field of research in both academia and industry. Recent advances have demonstrated application of tactile sensors in the area of biomedical engineering and opened up new opportunities for building multifunctional electronic skin (e-skin) which is capable of imitating the human sense-of-touch for medical purposes. Analyses have shown that current smart tactile sensing technology has the advantages of high performance, low-cost, time efficiency, and ease-of-fabrication. Tactile sensing systems have thus sufficiently matured for integration into several fields related to biomedical engineering. Furthermore, artificial intelligence has the potential for being applied in human-machine interfacing, for instance, in medical robotic manipulation, especially during minimally invasive robotic surgery, where tactile sensing is usually a problem. In this survey, we present a comprehensive review of the state of the art of tactile sensors. We focus on the technical details of transduction mechanisms such as piezoresistivity, capacitance, piezoelectricity, and triboelectric and highlight the role of novel and commonly used materials in tactile sensing. In addition, we discuss contributions that have been reported in the field of biomedical engineering, which includes its present and future applications in building multifunctional e-skins, human-machine interfaces, and minimally invasive surgical robots. Finally, some challenges and notable improvements that have been made in the technical aspects of tactile sensing systems are reported.

The sense of touch is involved in nearly all human activities, but information technologies for displaying tactile sensory information to the skin are rudimentary when compared to state‐of‐the‐art video and audio displays, or to tactile perceptual capabilities. Realizing tactile displays with good perceptual fidelity will require major advances in engineering, design, and fabrication. Research over several decades has highlighted the difficulties of meeting the required performance benchmarks using conventional devices, processes, and techniques. This has highlighted the important role that will be played by new material technologies that can bridge the electronic and mechanical domains. This must occur at the smallest scales, because of the great perceptual spatial and temporal acuity of the sense of touch. The requirements involved also furnish valuable performance benchmarks against which many emerging material technologies are being evaluated. This article highlights recent research and possibilities enabled through new material technologies, ranging from organic electronic materials, to carbon nanomaterials, and a variety of composites. Emerging material technologies are surveyed for the sense of touch, including sensory considerations and requirements, materials, actuation principles, and design and fabrication methods. A conclusion reflects on the main open challenges and future prospects for research in this area.

“…Haptic devices use magnetorheological fluid (MR fluid) to display tactile information that can be perceived during surgery [10][11][12][13][14][15][16][17]. The rheological properties of fluids containing dispersed ferromagnetic particles of 1-10 µm diameter drastically change under magnetic fields due to the formation of particle clusters.…”

The mechanical ability and usefulness of simulation systems can be improved by combining a tactile display with a remote control or medical simulation systems. In this study, a scissors-type haptic device containing magnetorheological fluid (MR fluid) in its fulcrum is developed. We evaluate the mechanical response to the applied voltage and realize the presence of mechanical stimuli when a subject grasps or cuts the corresponding objects. When the magnetic field around the MR fluid is controlled by an electric voltage of 150–500 mV, the torque linearly increases from 0.007 ± 0.000 to 0.016 ± 0.000 N m. The device can provide tactile stimuli with 0.1 s of resolution. We also determined the voltage profiles based on typical force profiles obtained during grasping/cutting processes and evaluated the torque using a mechanical evaluation system. Features of the force profiles related to the soft and sticky feels were reconstructed well.
