KIE 2007 BASIC ELECTROMAGNETICS SEMESTER 2, 2021/2022 GROUP ASSIGNMENT 1: ELECTROSTATICS (15%) SECTION 1: INTRODUCTION In this project (assignment), students are required to form a group of 4 students. Each group is required to develop an assignment project related to an electrostatic sensor for energy harvesting system. An electrostatic energy harvester with variable capacitor is shown in Figure 1 whose capacitance is a function of displacement distance of many elements. Design a sensor which will provide energy in the range of 1 to 20 microJoule (UJ) between the region bounded by the plates. Please write down also a MATLAB code that will calculate the energy as function of these displacement distances and compare. You may select appropriate technique for variable capacitor (choose one), dimensions, and dielectric materials which will produce this energy. eeeeeeeeee (a) the overlapping area RO R (b) (c) gap distance. overlapping electrode I Figure 1: Electrostatic energy harvester with variable capacitor
