“…Although piezoelectric materials can meet the need for a continuous power supply and provide an efficient way to harvest energy from the surrounding environment and the human body, problems in terms of mechanical, electrical, and thermal properties limit their application range. To overcome these drawbacks, piezoelectric composite materials have been produced by combining different non-piezoelectric and piezoelectric materials to achieve improved attributes . For example, the addition of BaTiO 3 crystals to poly(vinylidene fluoride–trifluoroethylene) (P(VDF-TrFE)) films enhance the performance of flexible wearable piezoelectric sensors .…”

The rapid maturation of smart city ecosystems is intimately linked to advances in the Internet of Things (IoT) and self-powered sensing technologies. Central to this evolution are battery-less sensors that are critical for applications such as continuous health monitoring through blood metabolites and vital signs, the recognition of human activity for behavioral analysis, and the operational enhancement of humanoid robots. The focus on biosensors that exploit the human body for energy-spanning wearable, attachable, and implantable variants has intensified, driven by their broad applicability in areas from underwater exploration to biomedical assays and earthquake monitoring. The heart of these sensors lies in their diverse energy harvesting mechanisms, including biofuel cells, and piezoelectric, triboelectric, and pyroelectric nanogenerators. Notwithstanding the wealth of research, the literature still lacks a holistic review that integrates the design challenges and implementation intricacies of such sensors. Our review seeks to fill this gap by thoroughly evaluating energy harvesting strategies from both material and structural perspectives and assessing their roles in powering an array of sensors for myriad uses. This exploration offers a comprehensive outlook on the state of self-powered sensing devices, tackling the nuances of their deployment and highlighting their potential to revolutionize data gathering in autonomous systems. The intent of this review is to chart the current landscape and future prospects, providing a pivotal reference point for ongoing research and innovation in selfpowered wireless sensing technologies.
