A flexible supercapacitor that integrates a wide application temperature range, satisfactory electrochemical performance and mechanical properties was fabricated by using anti-freezing anti-drying organohydrogels both as electrolyte binder of the combined electrode. The H2O molecules in organohydrogel are fixed 3D polyacrylamide network through hydrogen bond interaction ethylene glycol ionic hy...

Due to visual impairment and lack of social attention, the reading problem blind has not been well resolved. Many existing Braille devices still have many problems are accepted by public. This paper developed a portable system based on electrotactile display technology. The proposed is composed six-channel stimulator, flexible electrode array for graphical user interface (GUI) monitoring contro...
