Microdevices have been implanted in the body to diagnose diseases and treat functional disorders, such as an artificial sphincter for fecal incontinence. Since these devices are expected to work in the body as long as possible, the energy supply has become increasingly important. Wireless power transfer (WPT) systems are suitable for medically implanted devices. A transcutaneous energy transmission (TET) system, as one of the wireless power transfer systems, is discussed in this article. A TET system comprises two coils: a transmitter coil and a receiver coil. First, a serial-serial resonance circuit is adopted in the TET system by different resonance circuits’ efficiency analysis. In addition, coil features, such as magnetic field intensity, coil outer diameter, coil turns, and coil inner diameter, have been investigated in detail to improve the inductive coupling coefficient, leading to a high-power transmission efficiency. The proposed TET system with the optimal parameters is used in the in vivo experiments. Experiments using an optimized wireless power transfer system show a better performance than previous (before optimization) with a 38% increase in efficiency.

“…The earliest artificial anal sphincter is inspired by artificial urinary sphincter, which is used to treat urinary incontinence [ 6 ]. At present, the main artificial anal sphincters in clinical use include the American artificial bowel sphincter (ABS) [ 7 , 8 ], the Austrian soft anal band system (SABS) [ 9 ], the British artificial puborectalis anal sphincter system (PAS) [ 10 , 11 , 12 , 13 ] and the French magnetic bead chain artificial anal sphincter (Magnetic Anal Sphincter, MAS) [ 14 , 15 ]. Some progress has been made by these researchers.…”

Monitoring bodily pressure could provide valuable medical information for both doctors and patients. Long-term implantation of in vivo sensors is highly desirable in situations where perception reconstruction is needed. In particular, for fecal incontinence, artificial anal sphincters without perceptions could not remind patients when to defecate and even cause ischemic tissue necrosis due to uncontrolled clamping pressure. To address these issues, a novel self-packaging strain gauge sensor system is designed for in vivo perception reconstruction. In addition, long short-term memory (LSTM) networks, which show excellent performance in processing time series-related features and fitting properties, are used in this article to improve the prediction accuracy of the perception model. The proposed system has been tested and compared with the traditional linear regression (LR) approach using data from in vitro experiments. The results show that the Root-Mean-Square Error (RMSE) is reduced by more than 69%, which demonstrates that the prediction accuracy of the proposed LSTM model is higher than that of the LR model to reach a more accurate prediction of the amount of intestinal content. Furthermore, outcomes of in vivo experiments show that the robustness of the novel sensor system based on long short-term memory networks is verified through experiments with limited data.
