In this project, we plan to develop a flexible tactile sensing surface based on monolithic integration of flexible oxide-TFT-based active-matrix amplifier backplane and piezoelectric sensor arrays. In this three-year project, first we will focus on developing individual flexible oxide-TFT-based amplifiers for piezoelectric sensing application, and the corresponding amplifier circuit performance, in particular the dynamic characteristics, under the influence of mechanical strain/deformation will be studied. Two types of amplifiers will be implemented, including (i) self-bias feedback pseudo-CMOS amplifiers based on n-channel MgZnO or HfZnO TFTs and (ii) CMOS amplifiers based on n-channel ZnO and p-channel SnO TFTs. The device parameters will be optimized via SPICE simulation. Next, a 5&#61620;5 active-matrix oxide-TFT-based amplifier backplane will be fabricated on a typical 50 or 100 &#61549;m-thick free-standing polymer substrate and then integrated with a polyvinylidene fluoride piezoelectric sensor array via lamination and bonding techniques to demonstrate a flexible tactile sensor surface. At the same time, flexible ZnO/AlN multilayer piezoelectric sensor technology will be developed in parallel for the monolithic integration in the third year. In the last year of the project, we plan to move a step further by developing the tactile sensor surfaces on ultra-flexible polymer substrates (~ 10 &#61549;m) coated on temporary rigid carriers. The tactile sensor surface will be implemented by monolithic integration of active-matrix oxide-TFT-based amplifier backplane with the ZnO/AlN multilayer piezoelectric sensors via vacuum deposition. After the fabrication process completes, the ultra-flexible sensor surface will be mechanically released from the hosting support, and its performance will be evaluated when mounted onto curved surface with various curvatures.互補式氧化物薄膜電晶體技術可撓性電子可撓性壓電感測可撓性主動式陣列放大電路complementary oxide thin-film transistor technologyflexible electronicsflexible piezoelectric sensorflexible electronicsflexible piezoelectric sensorflexible active-matrix amplifier backplane主動式陣列氧化物薄膜電晶體放大電路與壓電感測整合之可撓性觸覺感測面之研究
