A flexible tactile sensor module based on polyimide matrix integrated with sensing elements and pluggable terminals connector was fabricated by polymer micromachining technology for robotic applications. The tactile sensor arrays are composed of $4{\times}4$, $8{\times}8$ and $16{\times}16$ sensing elements connected with pluggable terminals connector, respectively. Especially, both the tactile sensor array and the pluggable terminals are formed in the sensor module during the fabrication process. The fabricated tactile sensor module is measured continuously in the normal force range of $0{\sim}1N$ with tactile sensor auto-evaluation system. The value of resistance is relatively increased linearly with normal force in the overall range. The variation rate of resistance is about 2.0%/N in the range of $0{\sim}0.6N$ and 1.5%/N in the range of $0.6{\sim}1N$. Also, the flexibility of the sensing module is adequate to be placed on any curved surface as cylinder because the matrix consists of polymer and metal thin film.

Energy Storage System(ESS) is a system that maximizes energy efficiency by selectively storing and using the generated power when needed. Therefore, energy must be able to be charged or supplied at any time, and non-operating time should be minimized even in the case of failure or maintenance. However, current large-capacity energy storage systems must be shut down during maintenance due to structural problems. In this paper, we propose a PCS for 1MW ESS by configuring modular for large capacity ESS in parallel and verified of the hot swap technology that can replace, change, and repair the components that make up the system while keeping the system operating.
