“…The output voltage of the PHB/ePTFE TENG increased with the increase of vertical pressure. The effects of pressure and working hours on PHB-based TENGs had been investigated in our previous work . And all the tests on the triboelectric properties of the PHB/PLCL-ePTFE TENG were carried out with a mechanical force of 30 N in the mechanical exciter.…”

The rapid development of E-Skin has attracted researchers’ attention to portable wearable devices. However, it is a great challenge to achieve high-output performance and high-environmental protection simultaneously. Polyhydroxybutyrate (PHB) has excellent electron-withdrawing ability and biodegradability, but its stretching ability is poor, which limits its application in portable wearable devices. In this paper, the biocompatible poly(lactide-co-caprolactone) (PLCL) was innovatively selected to modify the properties of the PHB electrospun membranes, and PHB/PLCL composite membranes with different contents of PLCL were constructed. Then, the expanded polytetrafluoroethylene (ePTFE) membranes and PHB/PLCL electrospun membranes were used as the friction layers to construct a flexible triboelectric nanogenerator (TENG). With the increase of PLCL contents, the elastic recovery rate of the composite membranes increased to 68% of tension at 40% strain. The toughness of the composite membrane was increased by 546%, which exhibits ultratoughness and stretchable properties. Based on the ultratoughness and high elasticity electrospun membranes with 50% PLCL, a stretchable and large deformation sensing device was made. The PHB/PLCL-ePTFE TENG could distinguish pingpong and badminton accurately, as well as their various postures such as forehand, backhand, smash poses, etc., which provided a new idea for large deformation monitoring of TENGs.

With the growing demand for next-generation health care, the integration of electronic components into implantable medical devices (IMDs) has become a vital factor in achieving sophisticated healthcare functionalities such as electrophysiological monitoring and electroceuticals worldwide. However, these devices confront technological challenges concerning a noninvasive power supply and biosafe device removal. Addressing these challenges is crucial to ensure continuous operation and patient comfort and minimize the physical and economic burden on the patient and the healthcare system. This Review highlights the promising capabilities of bioresorbable triboelectric nanogenerators (B-TENGs) as temporary self-clearing power sources and self-powered IMDs. First, we present an overview of and progress in bioresorbable triboelectric energy harvesting devices, focusing on their working principles, materials development, and biodegradation mechanisms. Next, we examine the current state of on-demand transient implants and their biomedical applications. Finally, we address the current challenges and future perspectives of B-TENGs, aimed at expanding their technological scope and developing innovative solutions. This Review discusses advancements in materials science, chemistry, and microfabrication that can advance the scope of energy solutions available for IMDs. These innovations can potentially change the current health paradigm, contribute to enhanced longevity, and reshape the healthcare landscape soon.
