Acoustic Nonlinearity Parameter Estimation for Exoskeleton Control
IEEE Transactions on Medical Robotics and Bionics, 2021 The acoustic nonlinearity parameter of skeletal muscles changes with their contractions and has the potential to be utilized for exoskeleton control. In our previous work, a system comprising a wearable ultrasound probe was developed to estimate the acoustic nonlinearity parameter in vivo by measuring amplitudes of second-harmonic ultrasound.
