Resumen

The following work focuses on the development of a portable device capable of measuring finger diameter, using an adjustable iris mechanism. This device is characterized by its portability and its ability to perform precise measurements in real time in medical and sports contexts. Additionally, it has a Bluetooth connection that allows viewing and recording data on a smartphone, facilitating measurements in different contexts. The measurement was obtained in the range of 12.5 to 19.5 mm with an error of ± 4 mm. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2025.
