Influence of bimanual exercise on muscle activation in post-stroke patients
Springer Science and Business Media LLC - Tập 6 - Trang 1-11 - 2019
Matti Itkonen, Álvaro Costa, Hiroshi Yamasaki, Shotaro Okajima, Fady Alnajjar, Takatsune Kumada, Shingo Shimoda
Brain damage due to stroke often leaves survivors with lateral functional motor deficits. Bimanual rehabilitation of the paretic arm is an active field of research aimed at restoring normal functionality by making use of the complex neural bindings that exist between the arms. In search of an effective rehabilitation method, we introduced a group of post-stroke rehabilitation patients to a set of ...... hiện toàn bộ
GPU-accelerated surgery simulation for opening a brain fissure
Springer Science and Business Media LLC - Tập 2 - Trang 1-16 - 2015
Kazuya Sase, Akira Fukuhara, Teppei Tsujita, Atsushi Konno
In neurosurgery, dissection and retraction are basic techniques for approaching the site of pathology. These techniques are carefully performed in order to avoid damage to nerve tissues or blood vessels. However, novice surgeons cannot train in such techniques using the haptic cues of existing training systems. This paper proposes a real-time simulation scheme for training in dissection and retrac...... hiện toàn bộ
On-Chip Gel-Valve Using Photoprocessable Thermoresponsive Gel
Springer Science and Business Media LLC - Tập 1 - Trang 1-8 - 2014
Keitaro Ito, Shinya Sakuma, Yoshiyuki Yokoyama, Fumihito Arai
Microfluidic chips are powerful tools for biochemical experiments. High speed and precise flow control can be achieved by using microvalves on a chip. Several types of microvalves that can be integrated into a microfluidic chip have been reported. Among them, gel microvalves have certain advantages over other valves because of their soft structure, which will contribute to prevent mechanical damag...... hiện toàn bộ
Preliminary in vivo evaluation of a needle insertion manipulator for central venous catheterization
Springer Science and Business Media LLC - - 2014
Yo Kobayashi, Ryutaro Hamano, Hiroki Watanabe, Takuma Koike, Jaesung Hong, Kazutaka Toyoda, Munenori Uemura, Satoshi Ieiri, Morimasa Tomikawa, Takeshi Ohdaira, Makoto Hashizume, Masakatsu G. Fujie
Experimental assessment and prediction of design parameter influences on a specific vacuum-based granular gripper
Springer Science and Business Media LLC - Tập 11 - Trang 1-33 - 2024
Christian Wacker, Niklas Dierks, Arno Kwade, Klaus Dröder
Innovative soft robotic grippers, such as granular grippers, enable the automated handling of a wide spectrum of different geometries, increasing the flexibility and robustness of industrial production systems. Granular grippers vary in their design as well as in their configuration, which affects the specific characteristics and capabilities regarding grippable objects. Relevant aspects are the s...... hiện toàn bộ
Interaction force estimation on a built-in position sensor for an electrostatic visuo-haptic display
Springer Science and Business Media LLC - Tập 3 - Trang 1-11 - 2016
Taku Nakamura, Akio Yamamoto
This paper discusses a force sensing method using a built-in position sensing system for an electrostatic visuo-haptic display. The display provides passive haptic feedback on a flat panel visual monitor, such as LCD, using electrostatic friction modulation via multiple contact pads arranged on a surface-insulated transparent electrode. The display demonstrated in previous studies measured the pos...... hiện toàn bộ
Rubber artificial skin layer with flexible structure for shape estimation of micro-undulation surfaces
Springer Science and Business Media LLC - Tập 7 - Trang 1-12 - 2020
Mitsuhito Ando, Toshinobu Takei, Hiromi Mochiyama
In this paper, we propose a wearable tactile sensor for measuring the shape of micro-undulations on a hard surface. The proposed sensor has two layers. The inner one is a thin rubber layer into which a strain gauge is embedded that is formed around a user’s finger. The outer layer is a flexible structure that consists of numerous pins on a flexible sheet. The shape of micro-undulations on an objec...... hiện toàn bộ

Two-way least-incision transformable end-effector forceps for robot-assisted surgery
Springer Science and Business Media LLC - - 2015
Yuki Yamamoto, Ryoichi Nakamura
In laparoscopic surgery, smaller incisions produce good clinical results for patients. Therefore, there is a great need to develop thinner instruments for use in laparoscopic surgery. However, thinner instruments have smaller end effectors that limit the functionality of the instruments. To address this problem, we previously developed a new type of forceps that uses a least-incision transformable...... hiện toàn bộ
