“…With the assistance of Bluetooth technology, various wearable integrated systems were demonstrated to continuously monitor the ambulatory physiological information and muscle activities of farmworkers or athletes, and access stress levels during daily activities. [ 64–70 ] As a collective comparison, Table S3 (Supporting Information) lists the key characteristics of recently developed smart wearable systems, where it can be inferred that our system combining Wi‐Fi communication and customized platform serves as a promising alternative to realize both digitalized physical pressure sensing and direct visualization. In addition, the proposed hybrid device that uses both pressure sensing and visualization elements is further demonstrated for two applications: Morse code communication and wrist pulse monitoring (see Note S2 and Figure S9, Supporting Information).…”

A wearable interactive device that can synchronously detect and visualize pressure, stimuli will supplement easily identifiable in situ signals with conventional sensing that outputs only electronic signals. Currently, most interactive devices are composed of physically connected separate pressure sensors and display elements, which do not conform to the development of miniaturization and high integration. The realization of combining these two functions in one device with a simplified configuration is still only beginning to be explored. Inspired by the two-in-one response of the octopus, which can both sense and visualize stimuli, an integrated hybrid device based on ionic sensing and electrochromic display is proposed for interactive pressure perception. By efficiently reusing the electrodes and ionic gel, the device enables quantitative sensing and direct color changing in response to pressure. Benefiting from its excellent comprehensive performance, the applications are explored and verified, including the interactive perception of pressure information, hiding and display of visual information under pressure regulation, and repeated writing and erasing on flexible boards. Notably, multiple customized systems with improved design flexibility are implemented to provide remote monitoring and visual warning of behavioral states and physiological parameters. This study diversifies solutions to realize a direct link between pressure detection and visualization.

“…[ 23 ] Among various conductive materials, Au is the most used for the ultrathin soft sensor reviewed in this paper. [ 3,5,10,16,19,38,41,43,44,47,57,67,68,75a,80 ] Au has been widely used for biomedical devices with a great biocompatibility [ 19,81 ] unlike Ag and Cu, which require additional chemical treatment due to poor biocompatibility despite high conductivity. However, the downside is that gold is expensive.…”

Recent advances in soft sensors and flexible electronics offer various applications in detecting physical, electrical, and chemical signals. However, there are still technical barriers in current mechanical, electrical, and material properties for enhanced signal sensing. When measuring signals from the human skin, minimizing the skin‐sensor contact impedance is still challenging while maximizing sensitivity through optimized materials and soft electronics. Here, this review summarizes recent advances in materials, manufacturing, and integration technologies to develop ultrathin soft sensors for monitoring various human physiological signals. The enhancements in soft and compliant structures and mechanical properties are critical to making reliable wearable electronic systems. This article shares the details of soft sensors, integration processes, manufacturing methods, and their applications to target physical, electrical, and chemical signals. In addition, the limitations and current trends in developing multifunctional sensors, self‐powered devices, and integration with external stimuli systems are discussed.

“…Wearable medical devices have gained significant attention in recent years for their ability to approach clinical‐grade measurement quality while maintaining a convenient, often noninvasive form factor. These devices have seen use in disease detection, internet‐of‐things (IoT) systems as part of modular healthcare networks, [1] and remote health monitoring and telemedicine delivery, [2] among many other use cases. This review discusses recent wearable device advances based on the bio‐signals targeted by the device, the most documented of these in the literature we categorized as cardiovascular, locomotive, and neural.…”

Analysis & Sensing www.analysis-sensing.org Review doi.org/10.1002/anse.202200062Wearable devices have received significant attention recently for their ability to monitor critical physiological signals noninvasively, such as electrocardiography, electroencephalography, electromyography, and photoplethysmography. These biointegrated wearable systems can potentially fill gaps in conventional clinical practice by providing highly cost-effective health characterization and portable continuous health monitoring. Further, the physiological signals measured by wearables require post-processing to derive meaningful values, such as heart rate or blood oxygen saturation. This requirement, in conjunction with the smaller form factor and limited sensor count of the miniaturized systems, often necessitates robust signal processing and data analysis to approach the stringent performance specifications of conventional medical devices, and machine learning techniques have found success in filling this analytical role for their ability to learn complex functional relationships. Thus, this review outlines a systematic summary of the latest research on various wearable devices and their biosignal sensing and signal processing methods, emphasizing machine learning. We also discuss the developmental challenges and advantages of current machine-learning methods, while suggesting research directions for future studies.
