Solution Overview
Problem
Existing electromyography systems for micro-vertebrates face challenges in simultaneous measurement and are inconvenient for drug screening, as they require inserting micro-vertebrates into agarose gel or coil electrodes, making it difficult to maintain their lives during testing.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If micro-vertebrates are inserted into agarose gel or coil electrodes for measurement, then biological signals can be measured, but it is difficult to perform simultaneous measurement of multiple micro-vertebrates and maintains inconvenience for operation
Solution Approach 1:
The measurement system is segmented into multiple independent trap channels (first trap channel, second trap channel, etc.) within a single trap unit. Each trap channel can independently hold and measure one micro-vertebrate, enabling simultaneous measurement of multiple subjects without requiring separate agarose gel preparations for each, thus resolving the contradiction between measurement precision and operational convenience.
Solution Approach 2:
The trap unit serves multiple functions: it simultaneously holds multiple micro-vertebrates in separate trap channels, provides electrical connection through comparison electrodes for each channel, and enables parallel signal acquisition. This multi-functional design eliminates the need for repeated manual insertion operations while maintaining accurate biological signal measurement across all subjects.
2Measurement precision
If traditional electromyography systems are used for micro-vertebrates, then biological signals can be measured, but it is complicated to perform drug screening and inconvenient to operate
Solution Approach 1:
The invention adds a fluid delivery dimension to the traditional electromyography system by introducing an injection chamber connected to each trap channel. This enables drug administration through fluid injection while the micro-vertebrates are held in the trap channels, transforming the system from purely electrical measurement to integrated physiological measurement and drug delivery, thereby simplifying drug screening procedures.
Solution Approach 2:
The trap unit merges the functions of subject holding, electrical signal measurement, and drug delivery into a single integrated structure. The comparison electrodes are positioned to contact micro-vertebrates in the trap channels while the injection chamber provides drug administration, combining multiple experimental functions that were previously separate operations into one unified system.
3Measurement precision
If micro-vertebrates are fixed in traditional methods, then measurements can be taken, but it is difficult to maintain their lives during testing
Solution Approach 1:
Each trap channel provides a localized environment tailored to the specific needs of the micro-vertebrate it holds. The trap channel structure allows the micro-vertebrate to be positioned with its head oriented in a specific direction while maintaining contact with comparison electrodes, and the injection chamber delivers fluid locally to maintain hydration and vitality. This localized control of environmental conditions enables accurate measurement while preserving micro-vertebrate survival.
