A Real-Time and Energy-Efficient Implementation of Difference-of-Gaussian with Flexible Thin-Film Transistors

With many advantageous features such as softness and better biocompatibility, flexible electronic device is a promising technology that can enable many emerging applications. However, most of the existing applications with flexible devices are sensors and drivers, while there is nearly no utilization aiming at complex computation, because the flexible devices have lower electron mobility, simple structure, and large process variation. In this paper, we propose an innovative method that enabled flexible devices to implement real-time and energy-efficient Difference-of-Gaussian, which illustrate feasibility and potentials for the flexible devices to achieve complicated real-time computation in future generation products.
