Medical microfluidic chip temperature measurement

How can flexible sensors overcome the accuracy bottleneck in medical microfluidic chip temperature measurement?

In the genetic testing and drug screening of medical microfluidic chips, flexible temperature sensors of medical microfluidic chips are becoming the core solution to break through the limitations of traditional temperature measurement

1.1: Microchannel<1mm, rigid sensor cannot fit properly
1.2: Detection error caused by temperature drift (traditional sensor TCR>8000ppm/℃)
1.3: Biological sample activity is affected by temperature fluctuations

Our medical microfluidic chip flexible temperature sensor adopts a 0.05mm ultra-thin PI substrate, which can bend and attach<1mm microchannels. The TCR is only 6444ppm/℃ (20% lower than the industry average), ensuring A-level accuracy of ± 0.6 ℃.
2.1: Size advantage: 7 × 5mm miniaturized design (only 2mm wider than microchannels)
2.2: Material adaptation: Biocompatible coating (Parylene HT) to avoid sample contamination
After a certain genetic testing company used the sensor, the repeatability of microfluidic chip detection increased from 85% to 98%, which is the value of flexible temperature sensors for medical microfluidic chips.
2.3: Practical Case: Bio Bio Microfluidic Gene Testing Project
Scene: COVID-19 nucleic acid detection microfluidic chip (microchannel 0.8mm)
Solution: Customized 5 × 3mm flexible sensor array (with attached chip for import and export)
Effect: Temperature uniformity improved by 40%, detection time reduced by 25%
2.4: Selection Guide: 4 Key Parameters of Medical Microfluidic Sensors
Accuracy (± 0.6 ℃ vs Traditional ± 1.5 ℃)
Base material (medical grade PI/Parylene HT)
Response speed (seconds vs minutes)
