Abstract
Wireless capsule endoscopy(WCE)is a ground-breaking technique for a thorough examination of the small intestine. It is simple to use and causes less pain than conventional endoscopy. This thesis focused on designing a system for power transfer wirelessly to dispense with batteries. This must provide the largest percentage of energy transfer at long and near distances. In the first part of the thesis, a novel distance-based switch known as DbSWPT was developed. It has two capsule circuits and one bagger circuit (one for distances less than threshold distance “short distance” and one for distances more than threshold distance “long distance”). In this scenario, a switch is placed between two circuits based on the distance for selecting the best circuit. Moreover, another technique was proposed by using one capsule circuit, and two potentiometers in which one for short distances, and another for long distances. In this scenario, the switch is placed in front of two potentiometers to select the best one. The simulation results showed that in both techniques, the system efficiency decreases as the distance increase until it reaches the minimum efficiency at the predefined threshold distance, then it increases with increasing the distance after the threshold value. Furthermore, the proposed system focusses on the enhancement of the minimum efficiency at threshold distance by using distance-based switch topologies. The results illustrated that the system performance using series-series (S-S) configuration provided superior performance compared to parallel-parallel (P-P) configuration. It is found that the minimum efficiency for the proposed P-P distance-based switch is 51%, while for the proposed P-S is 83.33%. Accordingly, the proposed switch-based S-S configuration achieved minimum efficiency 90.91%. It increases efficiency by 8.34%. In the second part of this thesis, we proposed the use of UFMC for providing wireless communication system to obtain low Bit Error Rate (BER) performance for transmitting the captured image from WCE to the bagger circuit. We extensively studied the proposed communication system at the high negative values of the signal to noise ratio (SNR) as a challenging case. The results of UFMC on an endoscopy image showed average bit error rate (BER) of 0.0063, the maximum absolute error (MAE) of 0.0064, Pearson correlation coefficient (PCC) of 0.9779, root mean square error (RMSE) of 0.0797, and universal quality image (UQI) of 0.7253. Finally, it is concluded that the thesis provided
