“…Upon feet contact and separation with the ground, the static equilibrium state is broken and charges are transformed from body to ground to establish a new static equilibrium. 55 At the same time, the charges of SNC-TES are changed due to the electrostatic induction and the signal is generated. Besides, the arm contacts the SNC-TES when human is in motion and the external force is This journal is © The Royal Society of Chemistry 2024 exerted on SNC-TES, which makes the dual-mode triboelectric signal generated.…”

“…A portable ESD prevention system provides a negative charge to the human body through the TENG to keep the human potential stable. After that, the positive charge generated by contact charging of the TENG is compensated by the human movement process, which effectively prevents the ESD effect [ 84 ]. Meanwhile, an anisotropic TENG prepared from ordered nanopolymers obtained by electrospinning technology can be rotated 90° when not in operation, thus avoiding charge accumulation and circuit damage [ 85 ].…”

Triboelectric nanogenerators (TENGs) can not only collect mechanical energy around or inside the human body and convert it into electricity but also help monitor our body and the world by providing interpretable electrical signals during energy conversion, thus emerging as an innovative medical solution for both daily health monitoring and clinical treatment and bringing great convenience. This review tries to introduce the latest technological progress of TENGs for applications in biophysical sensors, where a TENG functions as a either a sensor or a power source, and in some cases, as both parts of a self-powered sensor system. From this perspective, this review begins from the fundamental working principles and then concisely illustrates the recent progress of TENGs given structural design, surface modification, and materials selection toward output enhancement and medical application flexibility. After this, the medical applications of TENGs in respiratory status, cardiovascular disease, and human rehabilitation are covered in detail, in the form of either textile or implantable parts for pacemakers, nerve stimulators, and nerve prostheses. In addition, the application of TENGs in driving third-party medical treatment systems is introduced. Finally, shortcomings and challenges in TENG-based biophysical sensors are highlighted, aiming to provide deeper insight into TENG-based medical solutions for the development of TENG-based self-powered electronics with higher performance for practical applications.

“…[ 10,11 ] At present, the charge injection method, including corona polarization [ 12 ] (CP), electrostatic ion gun, [ 13 ] and other technologies, [ 14,15 ] is the most widely used and effective surface charge injection method for triboelectric materials. However, the persistence of the injected charges is the most serious weak link for this kind of modification, which is always jeopardized by discharge, [ 16 ] air breakdown, and evacuation [ 17 ] caused by ambient humidity. Therefore, it is particularly important to develop simple methods to strengthen the stability of triboelectric charges, in order to achieve a breakthrough in the power density of TENG.…”

To achieve high charge density for the triboelectric polymer is a crucial task for fabricating triboelectric nanogenerators (TENGs). This work has developed a quenching polarization (QP) method to create ultrahigh and long‐persistent triboelectric charge on the triboelectric polymer with weak dipole polarity. The Ethylene chlorotrifluoroethylene copolymer (ECTFE) film can reach a charge density of 391 µC m−2 in the vertical contact mode by using this QP treatment, which is 200% higher than the result achieved by the most widely used method of corona polarization. The mechanism of the improvement through QP on the triboelectric properties is studied on the basis of the polarization induced grain refinement and interfacial trapping. The QP‐treated ECTFE can maintain ultra‐high charge density for both solid‐solid and solid‐liquid TENG. More interestingly, the charge induced by QP treatment is so persistent that it produces a recoverable discharging phenomenon for solid‐liquid TENG, which has never been observed before. This QP method provides a different approach for fabricating high‐performance triboelectric materials, while the QP‐induced changes in crystallization and tribo‐charge density can help to complete the physical understanding of the electrification mechanism of triboelectric polymer.
