“…Semiconducting organic materials like PCBM, PTB7-Th, PIPCP, have been proposed as alternatives to inorganic materials to overcome their drawbacks. Various nanomaterials and hybrid materials have been investigated in many fields like electronics and computing industries, [89,90] medical equipment, [91] transportation, [92] and solar cells. [93] Some eco-friendly, selfrepairing, and energy-harvesting materials are also to be explored in PPG sensing.…”

Photoplethysmography (PPG) technology enables the measurement of multiple physiological and psychological parameters with low‐cost wearable sensors and is reshaping modern healthcare. Advanced materials play a vital role in improving reliability and accuracy of PPG sensors. Recently, various advanced materials have been explored to optimize PPG sensor design, while some challenges exist toward large‐scale validation and mass production. This paper focuses on advanced materials applied in the photodetectors, light sources, and circuits of PPG sensors. The materials are categorized into four groups: inorganic, organic, nanomaterials, and hybrid materials. The properties and fabrication processes are summarized. Other technical details including the mode of operation, measurement sites, testing, and validation are discussed. The merits and limitations of the state of the art are highlighted to provide some suggestions for the future development of PPG sensors based on advanced materials.

“…These include silicene [3–6], germanene [3], stanene [7], phosphorene [8], geometrically-modified graphene [9,10], hexagonal boron nitride [11], and single-layer transition-metal dichalcogenides (i.e., MoS 2 [12], MoSe 2 [13], WS 2 [14], WSe 2 [15], and PtSe 2 [16]), which have received much attention in recent years. These new materials have the potential to revolutionize the materials industry due to their size and unique electronic, mechanical, thermal, and photonic properties [12,14,15,17,18] (for reviews and other references, see [19,20]). Because of their low dimensionality, small structural changes can significantly affect the transport and other physical properties of 2D materials [9,10].…”

“…In a typical SPM experiment, one measures the response of the sample to a point probe or a distribution of point probes. Interestingly, that is exactly the mathematical definition of the Green’s function – response to a point probe [22]. A Green’s function (GF) based method is, therefore, the natural choice for modeling SPM experiments on 2D materials.…”

A Green’s function (GF) method is developed for interpreting scanning probe microscopy (SPM) measurements on new two-dimensional (2D) materials. GFs for the Laplace/Poisson equations are calculated by using a virtual source method for two separate cases of a finite material containing a rectangular defect and a hexagonal defect. The prescribed boundary values are reproduced almost exactly by the calculated GFs. It is suggested that the GF is not just a mathematical artefact but a basic physical characteristic of material systems, which can be measured directly by SPM for 2D solids. This should make SPM an even more powerful technique for characterization of 2D materials.

“…These were lower, compared those of the neat polymers, reflecting decreases in the thermal stabilities. This alteration of thermal stability, together with the absence of peaks related to γ-PGA and CS in the thermograms of the nanoparticles, was indicative of interaction between the polymers (TEWARY & ZHANG, 2015). In thermal studies of chitosan nanoparticles loaded with GA 3 , Liu et al…”
