Flexible and stretchable strain sensors are expected to significantly contribute to new technologies and be applied in various applications, including human interfaces, smart clothes, and robotic skin. Hence, we have proposed a flexible film-shaped strain sensor that is composed of three elastomer films and two carbon-nanotube electrodes. It is thin, lightweight, and has low elasticity. Strain measurements...
Flexible and stretchable electronics are expected to contribute to electric conductors, sensors and actuators for various applications, such as robotic systems and power-assisted systems. In this study, a stretchable strain sensor is proposed as a length sensor for a pneumatic artificial muscle. To measure the length of the artificial muscle, the stretchable strain sensor is required to have quick...
Precise measurement of stretching and contration of pneumatic artificial muscles is required to realize applications such as human friendly robotic systems or nursing care support systems because the artificial muscles which are mainly made from elastic materials have non-linear characteristics. To measure the length of the artificial muscles directly, we propose a stretch-able strain sensor. The...
Conventional strain sensors measure strains exerted on solid metals and have been widely applied. Stretch measurements of flexible objects require strain sensors with wide dynamic range (stretch exceeding 100%) that can also measure areal changes. Flexible strain sensors are expected to realize a wide range of technologies, such as human interfaces, smart clothes, skin-motion monitoring, and robotic...
Pneumatic artificial muscles have advantages of lightweight, strong force, and electrical power saving for applications to power-assist systems or care support systems. These applications require precise control of artificial muscles. The artificial muscles have non-linear characteristics because they are mainly composed of elastic materials. The characteristics make the precise control difficult...
