<p>Arterial stiffness is used to diagnose atherosclerosis. The most commonly used estimation methods are indirect and non-invasive. To develop a method for direct measurement of the stiffness of blood vessels, stiffness estimation was performed on four simulated blood vessels with different stiffnesses values using a balloon catheter employed in the treatment of atherosclerosis. To measure the pressure response during balloon dilation in a simulated blood vessel, a pressurization and pressure measurement device was fabricated to pressurize the balloon catheter at a constant speed while measuring the pressure. To calculate Young's moduli of the simulated vessels, we simultaneously measured the pressure responses of the simulated blood vessels and the changes in circumferential length of the vessels using a microscope. A tensile test was also used to measure the Young's moduli of the simulated vessels. The Young's modulus values obtained by the balloon catheter method and the tensile test were compared. A linear relationship was observed between the Young's moduli determined by the two tests, indicating that the balloon catheter method can be used to estimate the Young's modulus of simulated blood vessels. To develop a simple method for estimating vessel stiffness, we calculated the reaction force received from a simulated vessel using the pressure difference during dilation in three balloon catheters with different diameters. We then evaluated whether the stiffness could be estimated by comparing the measured pressures with the Young's modulus values. Both the peak pressure after pressurization and the steady-state pressure during pressurization were related to the Young's modulus values, although the relationship depended on the diameter of the balloon catheter. Therefore, we suggest that it is possible to obtain values that reflect the Young's moduli of blood vessels using the balloon catheter method. These results suggest that with appropriate optimization of the balloon catheter diameter relative to the vessel diameter, this approach has the potential to provide pressure response values reflecting the stiffness of blood vessels.</p>

<p>The purpose of this paper is to design a path following control system based on the kinematics of the Lizard-Inspired Single-Actuated robot (LISA). LISA is a new type of robot that mimics the quadrupedal walking morphology of lizards with a four-bar linkage mechanism and can realize both propulsion and turning with 1 degree-of-freedom. To achieve this purpose, this paper takes 3 approaches: kinematics formulation, control system design, and numerical simulation. In the kinematics formulation, we formulate LISA’s turning angle, stride length, posture, propulsive direction, curvature, and position coordinate. In control system design, we design a control system that converges not only distance error but also the posture error and control input. Conditional equations that can achieve these 3 control targets are formulated using forward kinematics and reference path functions, and control inputs are obtained by solving the inverse problem. Numerical simulations verify the effectiveness of the designed control system using 3 types of trajectories: linear, circular, and a combination of circular and linear trajectories. As a result, it is confirmed that the designed control system is effective for all 3 types of trajectories and that not only the distance error but also the attitude and control input can be converged.</p>
