“…Several eye‐catching work of wearable PDs based on fiber substrates has been reported recently where nickel wires, titanium wires, Kevlar fibers, carbon nanotube (CNT) fibers, ZnO fibers, etc. were employed . According to current fiber based PDs, the most extensively used fibers for wearable PDs are metal fibers (for it can serve as an electrode as well as the reactant for photoactive material synthesis) and polymer fibers (for it can be reformed into any shape with little effort and serve as encapsulation material) .…”

Photodetectors (PDs), as an indispensable component in electronics, are highly desired to be flexible to meet the trend of next‐generation wearable electronics. Unfortunately, no in‐depth reviews on the design strategies, material exploration, and potential applications of wearable photodetectors are found in literature to date. Thus, this progress report first summarizes the fundamental design principles of turning “hard” photodetectors “soft,” including 2D (polymer and paper substrate‐based devices) and 1D PDs (fiber shaped devices). In short, the flexibility of PDs is realized through elaborate substrate modification, material selection, and device layout. More importantly, this report presents the current progress and specific requirements for wearable PDs according to the application: monitoring, imaging, and optical communication. Challenges and future research directions in these fields are proposed at the end. The purpose of this progress report is not only to shed light on the basic design principles of wearable PDs, but also serve as the roadmap for future exploration in wearable PDs in various applications, including health monitoring and Internet of Things.

the radiation emitted by the room-temperature object is mainly in the LWIR region, with the peak wavelength of about 10 µm. [1] Because of these two properties, photodetectors operating in the LWIR range are of significant importance for the heat-seeking technologies, such as all-weather surveillance, night vision, and missile guidance. To detect such lowenergy radiation by photon detectors, commonly used photosensitive materials are narrow-bandgap semiconductors (e.g., HgCdTe) and quantum wells (e.g., GaAs/ InGaAs). [2,3] For these photodetectors, the dark current at room temperature usually is large, and thus a cryogenic cooling unit is indispensable, which certainly increases the size and weight of photon detectors. Therefore, to miniaturize the volume and weight of LWIR detectors, the development of high-performance uncooled photodetectors is vital. Thermal detectors are well known for their ultra-broadband spectral response from UV to far-infrared and even to terahertz at room temperature. The excellent ability of terahertz radiation (0.1-1 mm) to penetrate through nonconducting materials renders it particularly attractive for applications in tomographic inspection. [4,5] Thermal detectors are based on the measurement of temperature-dependent properties, such as the resistance for bolometers, the temperature-difference-driven voltage for photothermoelectric (PTE) detectors, and the spontaneous polarization for pyroelectric (PE) detectors. The photoresponse in PE detectors depends on the variation of the spontaneous polarization vector with temperature; therefore, an external chopper is needed when measuring the power of continuous-wave (CW) radiation. For bolometers, an external bias is required, which introduces the extra 1/f noise. The typical temperature-sensitive materials in commercial bolometers are vanadium oxide (VO x ) or amorphous silicon. The main advantage of VO x lies in that its temperature coefficient of resistance is high (≈4% K −1 ) while the resistivity remains low, which is beneficial to reduce the noise level. [6] Detailed comparisons among different kinds of photodetectors are listed in Table 1.PTE detectors are based on the photothermal conversion and thermoelectric effect. As schematically shown in Figure 1, after absorbing the photons on one side of PTE detector, a temperature difference (ΔT) is built up, which drives the directed diffusion of charge carriers from the hot end to the cold end, establishing an electric potential difference (ΔU). This process High-performance uncooled photodetectors operating in the long-wavelength infrared and terahertz regimes are highly demanded in the military and civilian fields. Photothermoelectric (PTE) detectors, which combine photothermal and thermoelectric conversion processes, can realize ultra-broadband photodetection without the requirement of a cooling unit and external bias. In the last few decades, the responsivity and speed of PTE-based photodetectors have made impressive progress with the discovery of novel thermoelectric materials and ...

“…From the 1959 lecture, “There's Plenty of Room at the Bottom”, by the Nobel laureate Richard Feynman [ 1 ] to the 1985's first experimental discovery of the C 60 buckminsterfullerene lead by another Nobel laureate Harry Kroto [ 2 ], 21st-century communities have observed unstoppable integrity of nanomaterials with daily life in the last few decades. The extensive applications of nanomaterials include in almost all major scientific and commercial fields including semiconductor technologies [ [3] , [4] , [5] , [6] , [7] ], energy storage device [ [8] , [9] , [10] , [11] , [12] ], biological research [ [13] , [14] , [15] , [16] , [17] , [18] , [19] ], aerospace industries [ [20] , [21] , [22] ], constructions [ [23] , [24] , [25] , [26] ], foods [ [27] , [28] , [29] ], textiles [ [30] , [31] , [32] ], cosmetics [ [33] , [34] , [35] ] etc. These wide ranges of applications were made possible due to the availability of many different kinds of nanomaterials with various novel properties.…”

In this review article, we have presented a detailed analysis of the recent advancement of quantum mechanical calculations in the applications of the low-dimensional nanomaterials (LDNs) into biomedical fields like biosensors and drug delivery systems development. Biosensors play an essential role for many communities, e.g. law enforcing agencies to sense illicit drugs, medical communities to remove overdosed medications from the human and animal body etc. Besides, drug delivery systems are theoretically being proposed for many years and experimentally found to deliver the drug to the targeted sites by reducing the harmful side effects significantly. In current COVID-19 pandemic, biosensors can play significant roles, e.g. to remove experimental drugs during the human trials if they show any unwanted adverse effect etc. where the drug delivery systems can be potentially applied to reduce the side effects. But before proceeding to these noble and expensive translational research works, advanced theoretical calculations can provide the possible outcomes with considerable accuracy. Hence in this review article, we have analyzed how theoretical calculations can be used to investigate LDNs as potential biosensor devices or drug delivery systems. We have also made a very brief discussion on the properties of biosensors or drug delivery systems which should be investigated for the biomedical applications and how to calculate them theoretically. Finally, we have made a detailed analysis of a large number of recently published research works where theoretical calculations were used to propose different LDNs for bio-sensing and drug delivery applications.
