“…4 Because of properties such as low sheet resistance, high transparency, mechanical exibility and ease of deposition, AgNWbased electrodes are being evaluated for use in commercial touchscreen devices, 5 and have also been shown to be candidates for solar applications, 6-9 OLED displays, 11-13 touch panels, 14 and smart windows. 15 Furthermore, AgNW networks have recently been demonstrated for other applications including antibacterial lms, 19 wearable electronics, 5 transparent heaters, 10 sensors, [16][17][18] and medical devices. 20 There exist several reviews of AgNW transparent electrodes and their applications.…”

Silver nanowires are a promising replacement material for indium tin oxide in transparent electrodes. These nanowires, however, degrade in air due to corrosion and morphological instability. In this work, the composition of silver nanowire networks and common processing parameters used in electrode fabrication are tested for their effect on nanowire stability and electrode lifetime. Smaller diameter nanowires, sparser nanowire networks, higher electrode annealing temperatures and the use of a substrate plasma treatment are all factors which accelerate electrode degradation. The mechanisms of degradation are studied and suggestions to optimize silver nanowire electrode lifetimes are given.

“…55,[83][84][85][86] Moreover, for special working places like wound, the devices should be inhibitive to bacteria, in such cases silver nanoparticle or nanowire based substrate has been demonstrated to be effective. [87][88][89] Unlike traditional electronics, stretchable/ flexible devices are often supported or encapsulated by bad thermally conductive materials like polymer. Considering the sensitivity of human tissue to temperature rise, the temperature rise of the devices is an inevitable problem, when the heat generation of the devices increases with increasing integration density, especially those with power components.…”

Flexible inorganic bioelectronics represent a newly emerging and rapid developing research area. With its great power in enhancing the acquisition, management and utilization of health information, it is expected that these flexible and stretchable devices could underlie the new solutions to human health problems. Recent advances in this area including materials, devices, integrated systems and their biomedical applications indicate that through conformal and seamless contact with human body, the measurement becomes continuous and convenient with yields of higher quality data. This review covers recent progresses in flexible inorganic bio-electronics for human physiological parameters' monitoring in a wearable and continuous way. Strategies including materials, structures and device design are introduced with highlights toward the ability to solve remaining challenges in the measurement process. Advances in measuring bioelectrical signals, i.e., the electrophysiological signals (including EEG, ECoG, ECG, and EMG), biophysical signals (including body temperature, strain, pressure, and acoustic signals) and biochemical signals (including sweat, glucose, and interstitial fluid) have been summarized. In the end, given the application property of this topic, the future research directions are outlooked.

“…The latter offer advantages in higher lateral homogeneity, lower deposition temperature, and a certain stability under mechanical stress during bending [11][12][13][14]. A second development is the use of TCOs as functionalisation or protective layers in hybrid structures [15,16] or functionalised gas sensors [17], where with the advent of atomic layer deposition (ALD) it is possible to grow and employ very thin conformal layers of oxides [18][19][20]. In both of these cases, it is becoming increasingly difficult to assess the relationships between crystallographic order and electronic properties.…”

Crystallographic Characterisation of Ultra-Thin, or Amorphous Transparent Conducting Oxides—The Case for Raman Spectroscopy

et al. 2020

The electronic and optical properties of transparent conducting oxides (TCOs) are closely linked to their crystallographic structure on a macroscopic (grain sizes) and microscopic (bond structure) level. With the increasing drive towards using reduced film thicknesses in devices and growing interest in amorphous TCOs such as n-type InGaZnO 4 (IGZO), ZnSnO 3 (ZTO), p-type Cu x CrO 2 , or ZnRh 2 O 4 , the task of gaining in-depth knowledge on their crystal structure by conventional X-ray diffraction-based measurements are becoming increasingly difficult. We demonstrate the use of a focal shift based background subtraction technique for Raman spectroscopy specifically developed for the case of transparent thin films on amorphous substrates. Using this technique we demonstrate, for a variety of TCOs CuO, a-ZTO, ZnO:Al), how changes in local vibrational modes reflect changes in the composition of the TCO and consequently their electronic properties.
