When a blood glucose meter displays a number, what truly determines its accuracy is often hidden deep inside the test strip—materials you never see: conductive pastes and insulating inks.
At Betely, we are specialists in these critical core materials.
For more than 20 years, we have deliberately stayed away from finished medical devices, focusing instead on what matters most at the foundation level—building a stable signal system and a reliable reaction safety zone for blood glucose test strips. From the very start, we safeguard the accuracy of every measurement through materials science.
From Blood to Data: Materials as the Invisible Key Driver
1. Blood Sampling
A small blood sample is collected using a lancet.
2. Blood Glucose Test Strip
The strip includes a blood inlet end and a meter insertion end.
3. Blood Enters the “Reaction Boundary”
The blood flows into a precisely defined reaction area formed by insulating ink.
4. Glucose Reaction Occurs
Glucose reacts with enzymes, releasing electrons and generating a micro-current.
5. Signal Capture by Conductive Paste
Electrodes made with conductive silver paste or carbon paste accurately capture this micro-current and transmit it to the processor.
6. Result Displayed on the Meter
The glucose meter receives the signal, calculates the concentration, and displays the result on screen.
Behind this seemingly simple process lies a highly controlled materials system that determines whether the data can truly be trusted.
The Safety Zone: Betely Insulating Ink — the Solid Isolation Wall of Blood Glucose Test Strips
In enzyme-based reaction zones, Betely insulating ink acts as a precise “wall,” firmly fixing the reaction region in place.
Like a carefully drawn boundary, it ensures that enzyme–blood reactions stay exactly where they should—no deviation, no overflow.
Resistant to common contaminants such as alcohol residue and sweat, effectively shielding the reaction from external interference and preserving data authenticity.
Clean printing edges, excellent abrasion resistance, and long-term stability ensure consistent performance throughout the product lifecycle.
The Signal System: Betely Conductive Silver Paste & Carbon Paste — The Sensitive Nerve Lines of Blood Glucose Test Strips
Comparable to a noise-free radio signal, Betely conductive pastes deliver high signal fidelity with minimal deviation, achieving low CV values within ideal ranges.
Designed not to interfere with the enzymatic reaction between glucose and enzymes, ensuring pure and accurate detection.
Fast drying, strong adhesion, and excellent scratch resistance improve manufacturing yield and ensure smoother, more efficient production processes.
