The flexible and stretchable multifunctional sensors for the precise monitoring of the human physiological health indicators is an emerging requirement of next-generation electronics. However, the integration of multifunctional sensors into a common substrate for simultaneous detection of such signals without interfering with each other is the most challenging work. Here, we propose MXene-Ti3C2Tx and 3, 4-ethylene dioxythiophene (EDOT) deposited on laser-induced graphene (LIG/MXene-Ti3C2Tx@EDOT) composite-based flexible and stretchable multifunctional sensors for strain, temperature, and electrocardiogram (ECG) monitoring. In-situ electrophoretic deposition (EPD) of MXene-Ti3C2Tx@EDOT composite into LIG outperforms high strain sensitivity of 2,075, temperature coefficient of resistance (TCR) of 0.86%, and low skin-contact impedance. The sensor platform is integrated into an ultrathin and highly resilient polystyrene-block-poly(ethylene-ran-butylene)-block-polystyrene (SEBS). Finally, we demonstrate on-site detection of human body-induced deformations and physiological health indicators, such as temperature and ECG. The proposed approach paves a promising route to future wearables for smart skin and healthcare applications.

“…Therefore, metal nanowires are ideal materials to replace indium tin oxide (ITO) [10,11], carbon nanotubes [12], graphene [13,14] and conductive polymers [ [15] to fabricate TCFs. Among metal nanowires, silver nanowires (AgNW) is the most promising candidate owing to excellent conductivity, relatively low cost and convenient fabrication [16][17][18][19][20][21][22][23][24].…”

“…Nevertheless, some defects restrict the commercial application of AgNW TCFs, including difficulty in largescale production, personalized pattern and precision printing [25,26]. Currently, ultrasonic spray coating [27][28][29][30], spin coating [21], slot coating [31][32][33] and screen printing [7,[34][35][36][37][38][39][40][41][42][43][44] have been used for the large-scale production of high-quality TCFs. Wherein, ultrasonic spraying as an efficient method to produce large-sized TCFs, while it has to face with defects such as high surface roughness and poor uniformity.…”

Silver nanowire transparent conductive films (AgNW TCFs) were facilely prepared by screen printing conductive ink on a polyethylene terephthalate (PET) substrate, and the effects of ink compositions and oily stencil on the optoelectrical properties of AgNW TCFs were investigated in detail. 7.3 mg·mL-1 hydroxypropyl methylcellulose (HPMC), 4.12 mg·mL-1 AgNWs and 98T oily stencil allow the preparation of large-scale AgNW TCFs with high transmittance, low square resistance and high uniformity. The resultant screen printed AgNW TCFs possesses a sheet resistance as low as 13.0±0.6 Ω/sq, a transmittance of about 95.3% at 550 nm wavelength (deducting the background) and a haze of 3.86 (deducting the background), and can achieve a surface root mean square roughness of 3.33 nm, a film size of 15×20 cm2 and personalized pattern by means of the screen printing process. The transparent film heater (TFH) constructed by AgNW TCFs can rise to a usable temperature of 55°C at a low voltage of 4 V within 80 s. This process provides a simple strategy for fabricating uniform, patterned and large size AgNW TCFs for various devices.

In contrast to conventional methods for increasing the conductivity of transparent polymer electrodes based on additives, solvent treatment, or hot plate thermal processing, laser heating enables the selective annealing of defined areas of a material on the micrometer scale. This study investigates the spatial conductivity distribution of thin PEDOT:PSS films after selective heating by continuous wave (cw) laser radiation without damaging the material. The sheet resistances of the samples decreased abruptly above a certain threshold intensity and a changed relative permittivity of the irradiated material was detected by imaging ellipsometry. A theoretical model has been derived to estimate the resulting spatial conductivity distribution induced by the inhomogeneous heating with the Gaussian spatial intensity distribution of the applied laser radiation. In combination with the experimental measurements, the model revealed that the conductivity increased proportionally to the intensity above the threshold intensity, but remained unchanged below, resulting also in a Gaussian spatial conductivity distribution. Thus, in contrast to conventional oven annealing where only large-area averaged annealing is possible, laser annealing allows to tailor the spatial distribution of the conductivity on a micrometer scale opening applications for future micro systems.
