“…In endoscopy and catheter‐like surgery, flexible tools are needed that are less accurate but more suitable for navigation along tortuous paths and avoiding obstacles to reach distal organs. [ 152 ] Therefore, using advanced e‐skin sensors and actuators to detect the endoscope or catheter may be a way to overcome these shortcomings. In the field of soft electronics, emerging strategies that leverage the materials and manufacturing capabilities of the semiconductor industry are likely to offer direct opportunities in this area.…”

Recent advances in soft, flexible, and stretchable sensors have offered a good opportunity to design various types of wearable flexible medical devices for achievement of continuous health monitoring, preventive medicine and robot feedback and control. The integration of biofunctionability with electronic skin is undoubtedly an attractive prospect in the sense that the successful medical device requires good biocompatibility, sensing capability, and high degrees of mechanical flexibility. This work summarizes the last developments in electronic skin for next‐generation medical devices that can simultaneously detect a variety of physiological information of the human body. The key properties of e‐skin that must be realized for their versatile use in medical applications are discussed in detail. Next, the paper outlines the overall applications of these sensors in wearable medicine, implantable medicine, and interventional medicine, and emphasizes how these devices monitor human health status and may be expected to replace traditional clinical tools. Finally, the challenges and future research opportunities in the field of wearable health monitoring are proposed.

“…By changing the pressure-based sensing mechanism to a force-based sensing mechanism that improves the signal resolution at a higher contact angle between the catheter and blood vessel, Huang et al developed a miniature tactile sensor for a cardiovascular catheter [60] . The sensor consists of a compressible diaphragm with a highly sensitive strain gauge (thickness ~0.2 mm, height ~4 mm and diameter ~7 mm), a contact part (304 SS), a shelter part (304 SS) and an elastic rubber ring.…”

Interventional surgery has the advantages of small skin incision, little bleed loss, low postoperative infection and short recovery time, and thus has gradually become the preferred surgical approach over traditional open surgeries. Even though great achievements have been made towards clinical applications, limitations still exist, among which the loss of natural tactile perception of surgeons due to their indirect touch sense along the long catheter to the intervening human tissue is the crucial one. In recent years, researchers have dedicated great efforts in developing advanced medical catheters with smart tactile perception ability and made considerable progress. In this regard, we review the most recent development on the state-of-the-art miniature flexible and soft tactile sensors that are able to be integrated in the tip or on the side wall of medical catheters, with focus on the sensing mechanism, design requirement, device configuration and sensing performance of different types of sensors as well as their application demonstration in synthetic anatomical models and in-vivo animal experiment. After reviewing the representative research work, challenges that still exist are summarized and prospects toward future development are put forward.

“…The cannula is connected to an infusion tube, and the catheter-tip is the pressure sensing component in the transducer assembly. The transducer assembly conventionally utilizes MEMS technology to convert pressure waves into electrical signals [60,61] using silicon-based [62] and non-silicon based MEMS, such as Ti/Pt metallic wire coated with PI/SU [63], PEDOT: PSS with a Ag protective layer on a flexible PDMS substrate [64] and PVF 2 [65]. Other non-catheter-based pressure sensors include a capacitive-based bioresorbable POMaC/PGS/Mg on a (PHB/PHV) substrate sensor [66].…”

Advancements in materials science and fabrication techniques have contributed to the significant growing attention to a wide variety of sensors for digital healthcare. While the progress in this area is tremendously impressive, few wearable sensors with the capability of real-time blood pressure monitoring are approved for clinical use. One of the key obstacles in the further development of wearable sensors for medical applications is the lack of comprehensive technical evaluation of sensor materials against the expected clinical performance. Here, we present an extensive review and critical analysis of various materials applied in the design and fabrication of wearable sensors. In our unique transdisciplinary approach, we studied the fundamentals of blood pressure and examined its measuring modalities while focusing on their clinical use and sensing principles to identify material functionalities. Then, we carefully reviewed various categories of functional materials utilized in sensor building blocks allowing for comparative analysis of the performance of a wide range of materials throughout the sensor operational-life cycle. Not only this provides essential data to enhance the materials’ properties and optimize their performance, but also, it highlights new perspectives and provides suggestions to develop the next generation pressure sensors for clinical use.
