Description
Compare a supplied bend radius with a reference minimum.
Bench measurements require explicit signal units, calibration signs, geometry and reference conditions. Engineering strain differs from final-length ratio, secant stiffness differs from a material modulus, and nominal contact area differs from actual conductive contact. A supplied coefficient or certificate reference does not establish device validity.
Compare a supplied bend radius with a reference minimum.
When to use this tool
Use Wearable Bend Radius Ratio when you already have measuredRadius, referenceMinimumRadius and need to compare a supplied bend radius with a reference minimum.
How to use the tool and how it works
- Enter measuredRadius, referenceMinimumRadius. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read radiusRatio, margin. Use the output convention below.
Require measuredRadius>=0 and referenceMinimumRadius>0; return measured/reference and measured-reference.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| measuredRadius | Measured Radius | Required. Finite number; minimum 0. |
| referenceMinimumRadius | Reference Minimum Radius | Required. Finite number; strictly above 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| radiusRatio | Measured/reference-minimum radius; compares supplied geometry without establishing a suitable limit. | Required. Finite number. |
| margin | Margin | Required. Finite number. |

}Limitations and assumptions
- This geometric comparison assumes common units and a supplied reference. It does not establish material strain, fatigue, device fitness or a safe bending limit.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Use verified instrument records, calibration data and a complete device/material model. Evaluate uncertainty, operating conditions and appropriate professional requirements before interpreting local ratios or labels as performance, fitness or safety.
