Calibration and Testing of Flexi-force Sensor for IoT-enabled Rehabilitation Glove

The current developments in smart sensor technologies provide the foundation for industry growth and boost any nation’s economy. A smart sensor can be used as a high-precision measuring device in a large range of potential use cases like a smart biosensor can be used for monitoring patient health, diagnose disease, provide personalised therapy etc. To keep ideal levels of precision, smart sensor calibration with specific digital or electronic standards is required. The fundamental principles of building a robust National Quality Infrastructure (NQI) in any nation are calibration, standardization, accreditation and testing. In this study, five smart sensor flexi-force sensor calibrated under the use-case of developing an Internet of Things (IoT)-enabled rehabilitation glove for patients. The flexi-force sensors, effectively measures patient gripping strength at certain level of strength between 0 to 4.4lb. NIIRT performs the calibration of flexi-force sensors at lab with NABL accreditation adheres to stringent guidelines which employ cutting-edge machinery to guarantee accurate calibration outcomes report in India. According to the report, the calibration process demonstrated high precision with an accuracy of ±3 and an uncertainty of ±1. These results confirm the reliability and suitability of the flexi-force sensors for use in developing rehabilitation gloves, enhancing their potential for real-time healthcare applications.
