“…A recent study by Nat et al used heat and microwave radiation to make pyroprotein-based electronic yarns derived from com-mercial silks. [79] Through a process of heating to 650 °C and microwave irradiation, commercial silk textiles were converted to electrically conductive pyroproteins without the need for extremely high temperatures or harsh chemical treatments. [79] Effectively, by inducing conductivity in silk fibers, Nat et al has designed a method to remove one of the few demerits of silk as a hybrid material for electronic devices.…”

“…[61,74,75] Silk, also has a high degradation temperature [76][77][78] and can be pyrolyzed above temperatures of 800 °C. [79] In fact, the only property silk lacks for use in electronic yarns is intrinsic electrical conductivity.…”

“…From simple to complex materials, one only has to look at several examples from the above to see how silk will be used in the future. Carbonization of silk to replace fossil fuel derived conductive graphene, [135] biocompatible, thermally resistant, flexible fabrics, [58,63,79,147] scaffolds for biocatalytic reactions, [12,128] specific binding motifs for nanoparticle binding, [52] flexible triboelectric generators and photovoltaic devices, [90,91,142] and sutures that offer antibacterial activity, controlled drug release and active conductivity and monitoring [81] are but a few of the many examples of the future of silk based hybrid materials.…”

The energy demands that support modern industries and lifestyles are largely fulfilled by the burning of fossil fuels, [1] whose greenhouse gas by-products are a major contributing cause of global warming. [2] It has become clear that the combustion of fossil fuels at the current scale is unsustainable and more sustainable alternative energy sources must be explored to offset the contribution of fossil fuels. [3] Solar energy has an important role to play in this transition. Solar irradiation available on Earth's surface per hour far exceeds the annual global energy demand. [4] However, adaptation to solar energy has been slow due to a number of factors, such as rare or hazardous raw materials, high sensitivity to water, and short life spans. [5] Compared to the fossil fuel, which can be burned on demand, solar irradiation is subject to fluctuations caused by many factors such as weather conditions, time of the day, time of the year, and latitude. [6] Because storing solar radiation in its original form, that is, electromagnetic waves, is prohibitively difficult, its conversion prior to storage is necessary. Biological systems developed 3.5 billion years ago [7] as a process to use sunlight to drive chemical reactions through photosynthesis. Specifically, oxygenic photosynthesis, which occurs in most plants, algae, and cyanobacteria, converts carbon dioxide from the atmosphere into carbohydrates. These carbohydrates form dense and portable packets of chemical energy that can be released through cellular respiration whenever needed.The first step in following nature's example in turning light energy to chemical energy was enabled with the discovery of the photovoltaic effect by Edmond Becquerel in 1839, [8] in which the current generated by an electrochemical cell increased upon exposure to light. The first photovoltaic cells in the 19th century were based on pure metal species and exhibited low efficiencies. [9] Major efficiency improvements came in the 20th century with the incorporation of semiconductor materials into photovoltaic cells but they remained bulky and difficult to manufacture. [9] A breakthrough came in the 1980s with the advent of thin film solar cells which largely solved this problem. [9] Despite many advances, solar cells have a limited lifetime, and once their efficiencies have dropped to a no longer useful level, disposal becomes an issue due to the difficulty of recycling component materials. In addition, energy storage is often a major concern due to the limited number of hours per day photovoltaic devices are exposed to solar irradiation. Thus, Silk fibers are a remarkable material made of proteins possessing excellent mechanical properties that match or even outperform, in some aspects, high performance fibers such as Kevlar and steel. Silk proteins can be further produced recombinantly, allowing the possibility for genetic modification, enhancing silks' already impressive range of benefits. Thus far, little research has explored the possibility of incorporating silk-based materials in el...

“…[1][2][3] Electronic textiles (E-textiles) are a very promising technology that aims to revolutionize wearable electronics offering breathability, conformability and comfort to wear. 4 Despite all-textile individual electronic components 5 and integrated circuits have been demonstrated, 6 only few reports have attempted to achieve textile-based displays. 7 Thermochromic textile devices have already been demonstrated using metal oxide (such as CoO and Pb 3 O 4 ) and leuco dye or polymer (such as polydyne) through various methods of textile integration such as coating, 8 spinning, 9 and dyeing.…”
