“…Figure 2c presents the FTIR spectra of the electrodes. Compared to the references, [ 39,40 ] a band at 3400 cm −1 corresponds to O‐H stretching vibrations. Samples B and C exhibit a relatively strong peak at 3400 cm −1 , consistent with the higher water content of the PVA solution.…”

Self‐powered pressure detection using smart wearable devices is the subject of intense research attention, which is intended to address the critical need for prolonged and uninterrupted operations. Current piezoelectric and triboelectric sensors well respond to dynamic stimuli while overlooking static stimuli. This study proposes a dual‐response potentiometric pressure sensor that responds to both dynamic and static stimuli. The proposed sensor utilizes interdigital electrodes with MnO2/carbon/polyvinyl alcohol (PVA) as the cathode and conductive silver paste as the anode. The electrolyte layer incorporates a mixed hydrogel of PVA and phosphoric acid. The optimized interdigital electrodes and sandpaper‐like microstructured surface of the hydrogel electrolyte contribute to enhanced performance by facilitating an increased contact area between the electrolyte and electrodes. The sensor features an open‐circuit voltage of 0.927 V, a short‐circuit current of 6 µA, a higher sensitivity of 14 mV/kPa, and outstanding cycling performance (>5000 cycles). It can accurately recognize letter writing and enable capacitor charging and LED lighting. Additionally, a data acquisition and display system employing the proposed sensor, which facilitates the monitoring of athletes’ rehabilitation training, and machine learning algorithms that effectively guide rehabilitation actions are presented. This study offers novel solutions for the future development of smart wearable devices.

“…Due to the strong bands including Mo–C and Ti–C in MXene structure, the thermal stability of MXene was observed at even elevated temperatures. According to TGA plot of MnO 2 NWs, the weight loss (about 3.0%) occurred up to 1000°C because of the moisture removal and the phase conversion of MnO 2 into Mn 2 O 3 [ 39 ]. The weight losses occurred in three stages on TGA plot of MnO 2 NWs@Mo 2 TiC 2 nanocomposite owing to the moisture removal (1.8%) between 100 and 200°C, the removal of surface terminal groups in MXene structure and the phase conversion of MnO 2 into Mn 2 O 3 (about 4.0%) between 250 and 350°C.…”

A novel molecularly imprinted electrochemical sensor is presented based on one-dimensional ultrathin manganese oxide nanowires/two-dimensional molybdenum titanium carbide MXene (MnO2NWs@Mo2TiC2 MXene) for fenitrothion (FEN) determination. After the synthesis of MnO2NWs@Mo2TiC2 MXene ionic nanocomposite was successfully completed with a facile hydrothermal and the pillaring methods, a new type molecular imprinted electrochemical sensor based on MnO2NWs@Mo2TiC2 MXene was constructed with cyclic voltammetry (CV) polymerization including pyrrole monomer and FEN target molecule. After the characterization studies including spectroscopic, electrochemical and microscopic methods, the analytical applications of the prepared sensor were performed. A linearity of 1.0×10−9–2.0×10−8 mol L−1 was obtained and the values of the quantification limit (LOQ) and the detection limit (LOD) were 1.0×10−9 mol L−1 and 3.0×10−10 mol L−1, respectively. The studies of selectivity, stability and reproducibility of the constructed sensor based on MnO2NWs@Mo2TiC2 nanocomposite and molecularly imprinting polymer (MIP) were carried out in detail. Finally, the developed sensor was applied to white flour samples with the values close to 100%. Graphical Abstract

“…62 The TGA curve of pure MnO 2 possesses only one weight loss step due to the loss of moisture from an MnO 2 lattice (adsorbed water molecules). 63 Dynamic light scattering (DLS) data indicated that the synthesized MnO 2 NPs were stable and well dispersed in an aqueous medium with an average particle size of 278.5 nm and a polydispersity index (PDI) of 0.010 (Fig. S10 †).…”
