Robotic surgical platforms have seen increased use among minimally invasive gastrointestinal surgeons (von Fraunhofer et al. in J Biomed Mater Res 19(5):595–600, 1985. doi: 10.1002/jbm.820190511 ). However, these systems still suffer from lack of haptic feedback, which results in exertion of excessive force, often leading to suture failures (Barbash et al.(More)
This paper describes the design, microfabrication, and characterization of a miniature force sensor for providing tactile feedback in robotic surgical systems. We demonstrate for the first time a microfabricated sensor that can provide triaxial sensing (normal, x-shear, y-shear) in a single sensor element that can be integrated with commercial robotic(More)
This letter introduces a fabrication process for thick (&gt;50 &#x03BC;m) multipole electromagnets that produce fields exceeding 20 mT across 0.2-mm<sup>3</sup> free-space volumes. The novelty of the process involves the multistep thick-film electroplating of a magnetic alloy inside a high-density high-aspect-ratio solenoidal coil, producing high intensity(More)
