Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems face a tradeoff between increasing the length and area of reception electrodes to enhance signal intensity and minimizing impedance disturbance, which affects data transmission rates and signal quality, particularly at high frequencies, making it difficult to achieve both high-frequency and low-frequency signal intensity simultaneously.
Innovation Solution
A reception apparatus with multiple reception electrodes arranged opposing transmission lines and connection paths that include passive elements, such as resistors, inductors, or ferrite beads, to electrically connect adjacent electrodes, allowing for extended physical length while maintaining high self-resonance frequencies and improving coupling capacitances.

Engineering Contradiction Analysis
1Reliability
If the length and area of reception electrodes are increased to enhance signal intensity, then received signal intensity is improved, but impedance disturbance increases affecting data transmission rates and signal quality
Solution Approach 1:
The reception electrode is divided into multiple segments (first reception electrode and second reception electrode) separated by a gap. This segmentation allows the electrode structure to capture electromagnetic signals effectively while reducing the continuous conductive area that causes impedance disturbance, thus resolving the contradiction between signal intensity and impedance stability.
Solution Approach 2:
Different regions of the reception electrode structure are given different properties: the electrode segments have conductive properties for signal reception, while the gap region has insulating properties to prevent impedance disturbance. This local differentiation allows optimal performance in both signal intensity and impedance stability.
