Smart Socks

Muscular perimeter monitor for sport activities through 4 high resolution elongation sensors. Carried out for University of Valencia (CAFE)

Universidad de Valencia


Multiple inputs/outputs electronic design with conditioning circuits to precise reading of 4 elongation sensores simultaneously.


Periodic excitation logic for sensors. Data conversion and wireless transmission. Visual signs for video synchronization.


4 capacitive elongation sensors of high precision located in the calf muscle.


Server developed using Scala and JavaFX languages. This software initialyy calibrates the device, reads the sensors data, collects it and export it to external files to be further analysed


Box with 4 connectos, usb access, led indicators and slide switch. Manufactured in ABS (UL 94 HB). Location: waist, leg and arm.

Do you need to measure stretching ?
