With an improvement in technology and miniaturization of sensors, there have been attempts to utilize the new technology in various areas to improve the quality of human life. One main area of research that has seen an adoption of the technology is the healthcare sector. The people in need of healthcare services find it very expensive this is particularly true in developing countries.

This work reports an electro‐analytical study of NaCoO2 as cathode material synthesized by a low‐temperature combustion method for aqueous sodium‐ion batteries. The synthesized cathode material was electrochemically characterized in 2 M NaOH aqueous electrolyte. The obtained material‘s physical characteristics are investigated by X‐Ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Energy Dispersive X‐ray analysis (EDX), Thermo‐Gravimetric Analysis (TGA) and Differential Scanning Calorimetry (DSC) to evaluate its crystal structure, crystal size, composition, and surface morphology. From SEM images, the crystal size of the synthesized NaCoO2 is found to be varying between 50–100 nm with good crystallinity. From TGA studies, the material shows thermal stability up to around 300 °C with maximum weight loss at about 375 °C. Electrochemical behaviour of NaCoO2 in 2 M aqueous sodium electrolytes are evaluated using cyclic voltammetry and galvanostatic charge‐discharge techniques. The cell, NaTi2(PO4)3/2 M NaOH/NaCoO2 constructed in aqueous 2 M NaOH is found to deliver a discharge capacity of 89 mAh g−1 at C/10 rate. It retains its initial capacity over 55 cycles and at a high Crate of 1 C a discharge capacity of 34 mAh g−1 was obtained which can be compared with that obtained for NaCoO2 in non‐aqueous battery systems.

There are so many Error Correction Codes (ECC) have been using since decades to rectify one bit or multiple bits errors in the memory designs. To overcome the MCUs issue, Bose-Chaudhuri-Hocquenghem (BCH), Reed-Solomon codes and Punctured Difference Set (PDS) codes have been currently employed. In these conventional codes encoding and decoding is more complicated and need extra power, additional area, and huge delay and also in case of Content Addressable Memory (CAM) inserting cannot be employed due to tight coupling in between the cells. To substantiate the MCUs, issue a single-error rectification and two-fold location of integrated current Sensors are employed. To practically correct the MCUs error the new method called Bit Transition Encoder and Decoder (BTED) scheme is employed which are two dimensional matrix codes of data size 32 bits, which divides the information into the numerous sub information's like symbols of each 4-bits. The proposed BTED algorithm is implemented on Artix-7 FPGA development board and which is comparatively less delay and power in comparison with various existing methodologies. The simulation results shows that there is 18% improvement in delay, 15% in power reduction and 67% improvement in hardware resources utilizations compared to conventional algorithms.
