“…Material integrated sensing or the intrinsic sensing of energy storage devices can be hugely beneficial for applications such as wearable systems where the ever-increasing number of single-functionality devices is detrimental to user acceptance as it comes at the cost of comfort. , Likewise, in applications such as eSkin for robotics, such multifunctional devices could immensely help by lowering the number of sensors without sacrificing the richness of gathered data and at the same time reducing the overall weight of eSkin . Recently, the intrinsic sensing of devices such as solar cells (as touch sensors, in addition to energy generation), coil-based actuators (also used as touch sensors), antenna (as a temperature sensor, in addition to wireless data transmission), and flexible SCs (as mechanical strain sensors) , has been reported. However, the multifunctional use of energy storage devices has not been explored.…”

The increasing number of devices needed by wearable systems to bring radical advances in healthcare, robotics, and human−machine interfaces is a threat to their growth if the integration and energy-related challenges are not managed. A natural solution is to reduce the number of devices while retaining the functionality or simply using multifunctional devices, as demonstrated here through a stretchable supercapacitor (SSC) with intrinsic strain sensing. The presented SSC was obtained by electrodeposition of nanoflower MnO x on fabric (as a pseudocapacitive electrode) and three-dimensional conductive wrapping of poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) (PE-DOT:PSS) to boost the performance. Among fabricated devices, the stretchable PEDOT:PSS/MnO x /PEDOT:PSS supercapacitor (SPMP-SC) showed the best performance (specific capacitance of 580 mF•cm −2 (108.1 F•g −1 ); energy density of 51.4 μWh•cm −2 at 0.5 mA). The stretchability (0−100%; 1000 cycles) analysis of SPMP-SC with Ecoflex encapsulation showed high capacitance retention (>90% for 40% stretch). The intrinsic strain sensing of the SSC was confirmed by the linear variation of capacitance (sensitivity −0.4%) during stretching. Finally, as a proof-of-concept, the application of SSC with intrinsic sensing was demonstrated for health monitoring through volumetric expansion of a manikin during ventilator operation and in robotics and by measuring the joint angle of a robotic hand.

“…Moreover, the C p caused by the fringe effect on the edge of the capacitor can significantly distort the calibration of the sensor. [ 127 ] As a potential solution, a supercapacitor with high dielectric constant materials can considerably enhance the performance by improving sensitivity and value of capacitance, which relatively minimizes the effect of C p . For example, the urinary catheter with a supercapacitor pressure sensor array was reported to determine the presence of urinary infection.…”

A medical tool is a general instrument intended for use in the prevention, diagnosis, and treatment of diseases in humans or other animals. Nowadays, sensors are widely employed in medical tools to analyze or quantify disease‐related parameters for the diagnosis and monitoring of patients’ diseases. Recent explosive advancements in sensor technologies have extended the integration and application of sensors in medical tools by providing more versatile in vivo sensing capabilities. These unique sensing capabilities, especially for medical tools for surgery or medical treatment, are getting more attention owing to the rapid growth of minimally invasive surgery. In this review, recent advancements in sensor‐integrated medical tools are presented, and their necessity, use, and examples are comprehensively introduced. Specifically, medical tools often utilized for medical surgery or treatment, for example, medical needles, catheters, robotic surgery, sutures, endoscopes, and tubes, are covered, and in‐depth discussions about the working mechanism used for each sensor‐integrated medical tool are provided.

“…investigated a waterproof super capacitive sensor consisting of a coplanar electrode and a solid ionic gel electrolyte on a deformable membrane. [ 69 ] The deformation of the electrolyte membrane was induced by force and increased its contact area with the electrode, which resulted in the change of capacitance. The results show that the force sensitivity of 0.13 µF N −1 is 6 orders of magnitude higher than the 0.3 pF N −1 sensitivity of traditional capacitive sensors and can be used for numerous biomedical applications.…”

Cardiovascular diseases represent a significant threat to the overall well‐being of the global population. Continuous monitoring of vital signs related to cardiovascular health is essential for improving daily health management. Currently, there has been remarkable proliferation of technology focused on collecting data related to cardiovascular diseases through daily electronic skin monitoring. However, concerns have arisen regarding potential skin irritation and inflammation due to the necessity for prolonged wear of wearable devices. To ensure comfortable and uninterrupted cardiovascular health monitoring, the concept of biocompatible electronic skin has gained substantial attention. In this review, biocompatible electronic skins for cardiovascular health monitoring are comprehensively summarized and discussed. The recent achievements of biocompatible electronic skin in cardiovascular health monitoring are introduced. Their working principles, fabrication processes, and performances in sensing technologies, materials, and integration systems are highlighted, and comparisons are made with other electronic skins used for cardiovascular monitoring. In addition, we explore the significance of integrating sensing systems and the updating wireless communication for the development of the smart medical field. Finally, the opportunities and challenges for wearable electronic skin are also examined.This article is protected by copyright. All rights reserved
