A novel localized collocation solver based on Trefftz basis for potential-based inverse electromyography

作者：

Highlights：

• A novel localized collocation Trefftz method (LCTM) with cylindrical T-complete bases is presented for potential-based inverse electromyography (PIE).

• The proposed LCTM scheme performs more stable than the traditional CTM with a large number of discretization nodes.

• The proposed LCTM scheme is accurate and stable for reconstructing the electric potential even with 5% noisy boundary data.

• The morphology of LCTM reconstructed electromyography is similar to that of measured electromyography in sheep’s uterine contractions.
