Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In biochemical and pathogen detection, existing detection devices often fail to achieve sufficient contact between the detection recognition element and the to-be-detected substance, leading to incorrect detection results.
Innovation Solution
A detection device comprising interdigital transducers and a reaction layer, where surface waves are transmitted between the transducers to facilitate contact with a to-be-tested liquid, and a liquid-pushing device ensures the liquid reaches the reaction layer, allowing for accurate detection by comparing frequencies before and after interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the detection recognition element is placed in contact with the to-be-detected substance, then detection can be performed, but insufficient contact occurs leading to incorrect detection results
Solution Approach 1:
The patent employs surface acoustic waves (mechanical vibration) to propagate through the reaction layer and interact with the to-be-detected substance. The vibration energy enhances the contact between detection recognition elements and target substances, ensuring sufficient interaction for accurate detection while maintaining reliable measurement results
Solution Approach 2:
The patent introduces a reaction layer as an intermediary medium between the interdigital transducer and the to-be-detected substance. This reaction layer facilitates effective contact and interaction, enabling the detection recognition elements to reliably bind with target substances while maintaining detection accuracy
