A general theoretical analysis of a 3D generic TENG structure is presented. Using dimensionless formulation, it demonstrated that the optimal geometry does not depend on frequency moving dielectric but external ohmic impedance for maximum power output inversely proportional to frequency. It also found energy cube size TENG, square triboelectric charge density σT, and angular ω dielectric. In ca...

We designed 4x4 matrix TFTs arrays using current mirror amplifiers. Advantages of current mirror amplifiers are they need less requiring switches and the conversion time is short. The TFTs arrays 4x4 matrix using current mirror circuits have been fabricated and tested with success. The TFTs array directly can process signals coming from 16 pixels in the same node. This enables us to make the su...

The purpose of this paper is to show that ideas and techniques of the homotopy continuation method can be used to find the complete set of eigenpairs of a symmetric matrix. The homotopy defined by Chow, Mallet- Paret and York [I] may be used to solve this problem with 2""-n curves diverging to infinity which for large n causes a great inefficiency. M. Chu 121 introduced a homotopy equation...
