“…All of the various postoperative problems depend on the experience and judgement of the surgeon in the operative field. Recently, Mecdessay et al reported that the method for determining soft tissue balance used in total knee replacement arthroplasty (TKRA) was very inaccurate [7]. Moreover, they also noted that the use of pressure-based sensors increased the accuracy of knee balance determinations.…”

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, the TENG embedded in four different sides of the trial exhibits up to 1 V from peak-to-peak. Moreover, these flexible touch sensors with TENG describes a peak signal in output voltage which should lead to extremely sensitive detection of bearing friction induced by the THA.

“…In the case of total knee arthroplasty, a soft tissue balance check using a pressure-based sensor was conducted in the clinical eld and was shown to be highly reproducible compared to the hand check. [7] If such sensor base data accumulates, it will be possible to explain the post-operative dislocation or complications that are unknown. In addition, better postoperative results can be expected by using pressure data, as well as imaging data, to determine the length of legs during surgery.…”

Background: 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. Methods: In order to realize the flexible switch sensor, one of the elastomers, polydimethylsiloxane (PDMS), was introduced from the solution. Then, copper tape, which is made of metal, was attached to the produced PDMS film to make an electrode and connection was made with a wire. Afterwards, the fabricated TENG sensors are measured with output voltages through an oscilloscope. Results: The pressure-based sensor shows capability to sense bearing friction. In more detail, the TENG embedded in four different sides of the trial exhibits up to 1 V from peak-to-peak. Moreover, these flexible touch sensors with TENG describes a peak signal in output voltage which should lead to extremely sensitive detection of bearing friction induced by the THA. Conclusions: The conclusion of this study is that the TENG pressure-based sensor was able to detect friction in the THA bearing and detect the contact area of the bearing surface in the range of motion (ROM). Further research will be carried out to develop biocompatible sensors and to enable precise pressure-sensing.
