Method & Evidence

AimTo develop and validate a system for long-term monitoring of neuromusculoskeletal system performance using tattoo-like EMG sensors and dynamic modeling.

MethodExperimental and Modelling

ProcedureStretchable, tattoo-like dry surface EMG electrodes were applied to participants. Electromyogram (EMG) signals and hand grip force (HGF) were recorded during exercise sessions. An Autoregressive Moving Average model with Exogenous inputs (ARMAX) was established to relate EMG signal signatures to HGF. Model performance errors were tracked to quantify fatigue and recovery.
