“…Recent studies on using ultra-flexible electrodes [ 32 ] and electrode patches [ 33 ] deal mainly with measuring sEMG signals, especially in the submental area, for portable and remote monitoring of swallowing tasks and human-computer interaction, and focus on the materials and fabrication procedures; however, they do not address the optimal electrode configuration.…”

Surface electromyography (sEMG) can be helpful for evaluating swallowing related muscle activity. Conventional recordings with disc electrodes suffer from significant crosstalk from adjacent muscles and electrode-to-muscle fiber orientation problems, while concentric ring electrodes (CREs) offer enhanced spatial selectivity and axial isotropy. The aim of this work was to evaluate CRE performance in sEMG recordings of the swallowing muscles. Bipolar recordings were taken from 21 healthy young volunteers when swallowing saliva, water and yogurt, first with a conventional disc and then with a CRE. The signals were characterized by the root-mean-square amplitude, signal-to-noise ratio, myopulse, zero-crossings, median frequency, bandwidth and bilateral muscle cross-correlations. The results showed that CREs have advantages in the sEMG analysis of swallowing muscles, including enhanced spatial selectivity and the associated reduction in crosstalk, the ability to pick up a wider range of EMG frequency components and easier electrode placement thanks to its radial symmetry. However, technical changes are recommended in the future to ensure that the lower CRE signal amplitude does not significantly affect its quality. CREs show great potential for improving the clinical monitoring and evaluation of swallowing muscle activity. Future work on pathological subjects will assess the possible advantages of CREs in dysphagia monitoring and diagnosis.

“…Considering the relatively low portability of wired patches and motion artifacts caused by the alligator clip used above, Kim et al developed a wireless skin-mountable sensor patch system (Figure 10b) for remote monitoring of dysphagia. [189] The senor patch was composed of honeycomb-network electrodes and a strain gauge to detect EMG signals and strain waveforms. And the submental patch was connected to a potable self-powered Bluetooth module by using a soft conductive film wire instead of alligator clips.…”

On‐skin electrodes function as an ideal platform for collecting high‐quality electrophysiological (EP) signals due to their unique characteristics, such as stretchability, conformal interfaces with skin, biocompatibility, and wearable comfort. The past decade has witnessed great advancements in performance optimization and function extension of on‐skin electrodes. With continuous development and great promise for practical applications, on‐skin electrodes are playing an increasingly important role in EP monitoring and human–machine interfaces (HMI). In this review, the latest progress in the development of on‐skin electrodes and their integrated system is summarized. Desirable features of on‐skin electrodes are briefly discussed from the perspective of performances. Then, recent advances in the development of electrode materials, followed by the analysis of strategies and methods to enhance adhesion and breathability of on‐skin electrodes are examined. In addition, representative integrated electrode systems and practical applications of on‐skin electrodes in healthcare monitoring and HMI are introduced in detail. It is concluded with the discussion of key challenges and opportunities for on‐skin electrodes and their integrated systems.

“…In addition, by placing EMG sensor patches at different epidermal locations, they can be used to monitor muscle disorders such as dysphagia. 78 EOG measures potential variations between the inner and outer canthus, which is useful for monitoring eye movement and ophthalmological diagnosis. Different from other electrophysiological potentials, EOG measurements are usually carried out in DC potentials, which makes stable EOG signals challenging since DC recordings are susceptible to drift over time.…”

The recent advances in skin-interfaced wearable sensors have enabled tremendous potential toward personalized medicine and digital health. Compared with traditional healthcare, wearable sensors could perform continuous and non-invasive data collection from the human body and provide an insight into both fitness monitoring and medical diagnostics. In this review, we summarize the latest progress of skin-interfaced wearable sensors along with their integrated systems. We first introduce the strategies of materials selection and structure design that can be accommodated for intimate contact with human skin. Current development of physical and biochemical sensors is then classified and discussed with an emphasis on their sensing mechanisms. System-level integration including power supply, wireless communication, and data analysis are also briefly discussed. We conclude with an outlook of this field and identify the key challenges and opportunities for future wearable devices and systems.
