“…However, for many applications, multiple sensors measurement and comprehensive sensory integration are needed. Scalisi et al used inkjet printed flexible electrodes to measure multiple surface electromyography (sEMG) signals [ 10 ]. Or in homecare field, fallen alert, health monitoring, and exercise management require not only the measurement of movement, but also that of ECG, heart rate, temperature, and respiration.…”

The needs for light-weight and soft smart clothing in homecare have been rising since the past decade. Many smart textile sensors have been developed and applied to automatic physiological and user-centered environmental status recognition. In the present study, we propose wearable multi-sensor smart clothing for homecare monitoring based on an economic fabric electrode with high elasticity and low resistance. The wearable smart clothing integrated with heterogeneous sensors is capable to measure multiple human biosignals (ECG and respiration), acceleration, and gyro information. Five independent respiratory signals (electric impedance plethysmography, respiratory induced frequency variation, respiratory induced amplitude variation, respiratory induced intensity variation, and respiratory induced movement variation) are obtained. The smart clothing can provide accurate respiratory rate estimation by using three different techniques (Naïve Bayes inference, static Kalman filter, and dynamic Kalman filter). During the static sitting experiments, respiratory induced frequency variation has the best performance; whereas during the running experiments, respiratory induced amplitude variation has the best performance. The Naïve Bayes inference and dynamic Kalman filter have shown good results. The novel smart clothing is soft, elastic, and washable and it is suitable for long-term monitoring in homecare medical service and healthcare industry.

“…[17,[34][35][36] To improve device wearability and skin conformability, sEMG arrays have also been patterned using fractal geometries and microporous structures. [36] As alternatives to metallic contacts, metal nanowires and nanowebs, [37] as well as metal nanoparticles (MNPs), [19,28,38,39] have also been explored. MNP-based HDsEMG arrays have attracted particular attention because they can be fabricated using fast, additive inkjet printing (IJP), which is a high-throughput process with low material waste.…”

Wearable sensors for surface electromyography (EMG) are composed of single‐ to few‐channel large‐area contacts, which exhibit high interfacial impedance and require conductive gels or adhesives to record high‐fidelity signals. These devices are also limited in their ability to record activation across large muscle groups due to poor spatial coverage. To address these challenges, a novel high‐density EMG array is developed based on titanium carbide (Ti3C2Tx) MXene encapsulated in parylene‐C. Ti3C2Tx is a 2D nanomaterial with excellent electrical, electrochemical, and mechanical properties, which forms colloidally stable aqueous dispersions, enabling safe, scalable solutions‐processing. Leveraging the excellent combination of metallic conductivity, high pseudocapacitance, and ease of processability of Ti3C2Tx MXene, the fabrication of gel‐free, high‐density EMG arrays is demonstrated, which are ≈8 µm thick, feature 16 recording channels, and are highly skin conformable. The impedance of Ti3C2Tx electrodes in contact with human skin is 100–1000× lower than the impedance of commercially available electrodes which require conductive gels to be effective. Furthermore, the arrays can record high‐fidelity, low‐noise EMG, and can resolve muscle activation with improved spatiotemporal resolution and sensitivity compared to conventional gelled electrodes. Overall, the results establish Ti3C2Tx‐based bioelectronic interfaces as a powerful platform technology for high‐resolution, noninvasive wearable sensing technologies.

“…While losing in terms of surface density in comparison to other fabrication processes, the processing time is rapid and the waste of material very low. Moreover, inkjet printing technology resolution is good enough for such envisaged applications here . Silver nanoparticle ink is patterned on top of the polyimide substrate as first low‐resistivity layer providing: (i) the connection electrodes which are connected to the sEMG recording system, (ii) the interconnection tracks until electrodes location, and (iii) the basement for active electrodes sites.…”

PSS MEAs record electrophysiological activity signals that are comparable to those obtained with unitary Ag/AgCl commercial electrodes. Additionally, such MEAs offer parallel and simultaneous recordings on multiple locations at high surface density. It also proves its suitability to reconstruct an innervation zone map and opens new perspectives for a better control of amputee's myoelectric prostheses. The employment of additive technologies such as inkjet printing suggests that the integration of multifunctional sensors can improve the performances of ultraflexible brain-computer interfaces.
