“…There have been extensive research activities on flexible electronics based on polymeric materials . Flexible TFT (thin film transistor) [1][2][3][4][5][6][7][8][9][10][11], flexible flat panel displays including organic light emitting diodes (OLED) [12,13] and liquid-crystal displays (LCD) [14], sensors [15][16][17], microelectromechanical systems (MEMS) [18], photovoltaic devices [19,20] and FPCB (flexible printed circuit board) [21] based on all polymeric materials or partial employment of polymeric materials have been developed due to low-cost and ease of fabrication. It is expected that flexible microelectromechanical (MEMS) and semiconductor devices as well as flexible displays can be fabricated on flexible substrate for many applications in the future.…”
