Abstract Objective In this research. a triboelectric nanogenerator (TENG) was utilized to determine if a pressure-based sensor could detect bearing friction in a total hip arthroplasty (THA) and detect the contact of specific areas during ROM checks. Results The pressure-based sensor shows capability to sense bearing friction. In more detail. https://www.mariameetsanna.com/product-category/outliner-ii-3-prong-corded-trimmer/
