The paper presents a support device for nursing. Several prototypes of assistive devices for feeding gastrostomy have been proposed to provide appropriate pressure for the pressurized bag. A control method for force detection has been also presented. Effectiveness of the proposed device have verified by nurses at hospitals.
Submerged floating tunnel (SFT) has been considered as an interesting structure to connect the banks separated by a narrow and deep sea. Reinforced concrete (RC) tunnels have been suggested as SFT structures. Because the governing load of a SFT is bending moment, a structure with enhanced stiffness and ductility will be useful for a SFT. Therefore, new-type structures which have superior stiffness...
A new type of continuum manipulator is presented, in which the body of the device is made up of identical, repeated interlocking fibers. A working prototype is demonstrated. Basic models describing the kinematics and mechanical properties of the device are developed, and their predictions are compared with the performance of the physical prototype. Advantages of the interlocking design include improved...
The aim of a European project Nephron+ is design of a wearable artificial kidney device (WAKD). This paper is focused on design of the corresponding ultralow-hemolysis continuous-operation blood pump. Accurate specifications and operating principle of the pump are determined; a first, non-optimal configuration of an electro-mechanical actuator which will be used to pump the blood is designed; its...
This paper reports a prototype implementation of 3D Fluid-Structure Simulation. In this implementation, heartbeat fluid flows inside a rectangular tube where the operator can interactively change the width of the tube. In order to achieve interactive simulation speed, some parts of the simulation is accelerated by GPU. For further improvement of the simulation speed, two techniques have been examined:...
Biological cells have a variety of high performance functions using chemical energy from oxygen and nutrients and no electrical energy. We have proposed a novel use of pulsating heart cells as mechanical micro actuators. Here we propose a novel bio-actuated power generator combined with the contractile force of heart muscle cells and piezoelectric fiber as a material combination to convert vibrational...
In this paper, a first prototype of a multifunctional tactile sensor using ionic polymer metal composites (IPMCs) is proposed, designed, and tested. Two IPMC strips are used, one as an actuator and one as a sensor, both positioned in a cantilever configuration; working together they enable the system to detect the presence of a material in contact with it and to measure its stiffness. These sensing...
