Abstract

Recent progress on two-dimensional layered nanomaterials supported wearable biomedical sensors and power devices is comprehensively reviewed.

Synergistic Doping and Intercalation: Realizing Deep Phase Modulation on MoS2 Arrays for High‐Efficiency Hydrogen Evolution Reaction

“…Furthermore,t he wavelet transform (WT) of Mo K-edge EXAFS oscillation further displays visually atomic dispersion of Mo for these samples due to its capability to separate backscattering atoms in both R-space and k-space resolution. [28,31,32] In Figure 3d,the WT plot of MoS 2 /VGshows two maximums at 1.93 and 2.92 ,r espectively,w hich are associated with the Mo À Sand Mo À Mo bonding,implying the successful preparation of MoS 2 .Asfor PO 4 3À -MoS 2 /VG, MoÀ Sand MoÀMo bonding can be clearly observed and the PÀMo bond is absent, in good agreement with the above results. Particularly noteworthy is that the value of intensity maximum is mainly related to different coordinates (R, k), whose location is connected with the path length and atomic number of the scattering atoms.Asseen from the WT contour plots of MoN 2 ,t he ka nd Rv alues of intensity maximum can be observed at 9.5 À1 and 1.45 ,r espectively,w hich is associated with Mo-N path.…”

Recent progress in tactile sensors and their applications in intelligent systems

“…The emergence of various new materials and new technologies has enabled biomedical tactile sensors to be miniaturized, multifunctionalized, integrated and made intelligent. At present, thermosensitive biomedical sensors, FET biomedical sensors, piezoelectric biomedical sensors, triboelectric biomedical sensors and photosensitive biosensors have been widely used in biomedical research [102].…”

Stretchable Supercapacitors as Emergent Energy Storage Units for Health Monitoring Bioelectronics

“…[257,258] Therefore, reliable integration of stretchable supercapacitors and sensors have been of great significance in many biomedical applications. Information collected from these sensors can then be used for early diagnosis and therapeutic decision making.…”
