Prussian blue‐based inorganic flexible electrochromism glucose sensor

Abstract: Flexible inorganic Prussian blue (PB) containing electrode hcas been synthesised using a simple electrodeposition technique for dual functions in electronics (electrochromism) and biology (glucose sensing) applications. Structural and spectroscopic characterisations of the fabricated film have been done using electron microscopy and Raman spectroscopy. Flexible inorganic electrochromic device is one of its kind having promising features with colour contrast (50%), coloration efficiency (80 cm 2 /C) and robust … Show more

“…A simple and very efficient bottom up approach, named as the hydrothermal method [13,32], due to its ease as compared to other techniques like etching, spray pyrolysis and so forth [33][34][35][36], has been used for preparing the nanostructured film consisting of Ni and Co backbone. The raw precursor of Ni (NO 3 ) 2 .6H 2 O and Co(NO 3 ) 2 .6H 2 O bought from Sigma Aldrich (>99% purity) and mixed in 1:2 M ratio in a 30 ml aqueous medium.…”

“…In general, inorganic electrochromic active species are known for their poor EC performances in terms of large switching time and weak stability [14]. Different approaches have been incorporated to resolve such bottlenecks in the inorganic family by modifying the electrochromic device (ECD) with the formation of nano morphology-based EC active material, double layer ECD, hybrid ECD and so forth [4,14,31]. Therefore, every study for fabricating the EC active electrode should be in favour of modifying such EC parameters.…”

“…In the current era of nanoscience and nanotechnology, low-dimensional materials, especially semiconductors, have attracted much attention because of their technologically important tunable electronic [5,6] and opto-electronic properties, delivering promising potentials in many fields such as energy storage, [7][8][9][10][11] conversion, [12] and sensors, [13][14][15][16][17] in comparison with their bulk counterparts and have gained enormous attention from researchers. In particular, silicon (Si) nanostructures (NSs), including porous Si, [18][19][20][21][22][23][24][25] Si nanowires (SiNWs), and fractal porous SiNWs, are of special interest as they exhibit superior opto-electronic properties with improved device performance, such as narrower spectral line width, low threshold current densities, [26] and reduced temperature sensitivity.…”

“…17 Kumar et al synthesized a flexible inorganic PB-containing electrode using a simple electrodeposition technique for dual functions in electronics and biology applications, which has promising features for wearable electronics application. 18 However, as an inorganic ECM, PB still has defects, that is, monotonous color, low contrast, and slow response time, among others. Many methods have been used to overcome these shortcomings, such as compositing with conducting polymers 19 and carbon nanomaterials, 14,20−22 including carbon nanotubes, graphene, and carbon dots.…”
