“…Most researchers achieve the purpose of self-powered sensors by integrating energy harvesters. For example, by using an integrated piezoelectric energy harvester, Yu et al developed the self-powered piezoelectric tactile sensor [ 60 ]. In order to achieve self-power supply, it can also employ thermoelectric or photoelectric materials.…”

With the arrival of the Internet of Things era, the demand for tactile sensors continues to grow. However, traditional sensors mostly require an external power supply to meet real-time monitoring, which brings many drawbacks such as short service life, environmental pollution, and difficulty in replacement, which greatly limits their practical applications. Therefore, the development of a passive self-power supply of tactile sensors has become a research hotspot in academia and the industry. In this review, the development of self-powered tactile sensors in the past several years is introduced and discussed. First, the sensing principle of self-powered tactile sensors is introduced. After that, the main performance parameters of the tactile sensors are briefly discussed. Finally, the potential application prospects of the tactile sensors are discussed in detail.

“…Furthermore, nanocomposite piezoresistive pressure sensors and energy harvesters have exhibited promising results. An innovative ZnO/Ti 3 C 2 T x -based device generated 10 μW at approximately 16 kPa [24], while a nano-engineered carbon-fiber-based piezoelectric smart composite achieved voltage outputs ranging from 1.4 to 7.6 V under impact acceleration of 0.1-0.4 ms −2 . Additionally, a PVDF-BTO Nano-composite device demonstrated a maximum output of 4.1 V under finger-tapping conditions [24][25][26].…”

Wireless implantable devices (WIDs) have the potential to revolutionize biomedical sensing, but their power supplies face significant challenges. Traditional energy transfer methods such as inductive and RF have limitations due to associated tissue losses. This work demonstrates a promising approach to this problem, using a flexible implantable ultrasound energy harvester (IUEH) made of biocompatible Poly (vinylidene fluoride-co-trifluoro ethylene) (P(VDF-TrFe)) free-standing film. Unlike commonly used piezoceramic devices, IUEH can be fabricated using economical solution processing methods such as spin coating. In addition, the PVDF-TrFE Ultrasound energy harvesters are rarely reported in the literature. The device performance of the polymer IUEH was investigated in air, water, and animal meat tissue, and the results show that it can generate a power output of 1.1 mW/cm2 in meat, and 1.4 mW/cm2 in water at 80 kHz. The device fabricated using a free-standing piezoelectric thin film, offers an optimum output that is comparable to other P(VDF-TrFe) based high-frequency devices. Additionally, its flexible design, lower costs, and biocompatibility make it a promising alternative to lead-based devices; thus, offering safety, affordability, and quick customization, while promoting minimally invasive procedures and driving innovation in medical device development.

In the past decade, with the rapid development of wearable electronics, medical health monitoring, internet of things and flexible intelligent robots, flexible pressure sensors have received unprecedented attention. As a very important kind of electronic components for information transmission and collection, flexible pressure sensor has gained a wide application prospect in the fields of aerospace, biomedical and health monitoring, electronic skin and human‐machine interface. In recent years, MXene has attracted extensive attention because of its unique two‐dimensional layered structure, high conductivity, rich surface terminal groups and hydrophilicity, which has brought a new breakthrough for flexible sensing. Thus, it has become a revolutionary pressure sensitive material with great potential. In this work, the recent advances of MXene‐based flexible pressure sensors is reviewed from the aspects of sensing type, sensing mechanism, material selection, structural design, preparation strategy and sensing application. The methods and strategies to improve the performance of MXene‐based flexible pressure sensors are analyzed in details. Finally, the opportunities and challenges faced by MXene‐based flexible pressure sensors are discussed. This review will bring the research and development of MXene‐based flexible sensors to a new high level, promoting the wider research exploitation and practical application of MXene materials in flexible pressure sensors.This article is protected by copyright.
