    Nilesh A. Lakade, Shankar D. Nawale
    Ssrg International Journal of Electrical and Electronics Engineering, 2025
    This study presents the design, analysis, and implementation of a rectenna system (rectifying antenna) optimized for RF energy harvesting in IoT applications. With the exponential growth of low-power IoT devices, sustainable power solutions are increasingly critical. Our work introduces a novel heptagonal patch antenna with strategically placed slots functioning at 2.45 GHz. The design fabricated on FR4 achieves a substantial gain improvement from 2.63 dBi to 6.1 dBi at 2.45 GHz and 11.5 dBi at 2.42 GHz through the integration of a reflector positioned 20 mm behind the antenna. A voltage doubler rectifier circuit utilizing SMS7630-079LF Schottky diodes successfully converts the harvested RF energy to DC power. The proposed rectenna provides a DC output voltage (VDC) of 180.8 mV placed at 45 cm from the commercial Wi-Fi router, demonstrating the solution's suitability for powering low-energy IoT devices. This cost-effective approach addresses key issues in IoT deployment by eliminating dependencies on conventional batteries and providing a sustainable alternative power for smart city applications, including agriculture, healthcare, smart factories, and transportation.

The proposed solution architecture measures its performance through scalability, latency and throughput metrics. we developed a custom smart contract through optimized state control logic and low gas costs and efficient batch processing functions. The architecture ensures high-throughput operation because it keeps transaction processing times short for large transaction volumes. The system evaluation shows latency results between <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$\mathbf{1 8 0} \boldsymbol{-} \mathbf{2 5 0}$</tex> milliseconds with throughput results between 50–60 transactions per second and batch processing capabilities between 1,000 and 10,000 transactions which demonstrates its scalability and responsiveness. The framework offers an effective solution against counterfeit drugs using secure blockchain execution of IoT device data while preserving supply chain integrity and transparency and maintaining operational efficiency.
  • Traceability and Verification to Prevent Counterfeit Drugs: A Secure, Efficient Pharma Supply Chain with IoT-Enabled Blockchain and Smart Contracts
    Rahul Konapure, Shankar Nawale
    Ssrg International Journal of Electronics and Communication Engineering, 2025
    Currently, the stakeholders involved in the pharma supply chain are manufacturers, distributors, retailers, and patients. The process is excessively complicated, offers minimum transparency and accountability, and appears poorly protected from counterfeiting. This paper proposes a novel integration of Internet of Things (IoT) sensors, blockchain technology, and Role-Based Access Control (RBAC), creating a transparent, immutable ledger that ensures the authenticity and visibility of drugs throughout the supply chain. IoT sensors provide real-time tracking of environmental conditions and moments of drugs, while blockchain technology ensures a secure, tamper-proof record of every transaction, enhancing traceability through the supply chain. Role-Based Access Control strengthens security by limiting access to sensitive data according to the roles of different stakeholders. The use of Smart contracts simplifies processes, as it removes intermediaries and ensures secure transaction histories. This integrated approach addresses counterfeiting and transforms pharmaceutical supply chain management by improving transparency, security, and efficiency. Enhanced blockchain performance facilitates more effective drug delivery, ultimately improving patient outcomes. By utilizing these advanced technologies, the proposed system significantly reduces risks associated with counterfeiting and supply chain disturbances, ensuring the delivery of safe and effective medications to patients.

    International Journal of Electrical and Electronics Research, 2024
    This paper presents the performance comparison of various nonlinear elements in frequency multiplying circuits for low power wireless applications. An analysis and design are derived. Passive frequency multipliers take advantage of the nonlinear behavior of passive circuit components. Passive frequency multipliers take advantage of the nonlinearity of passive circuit components. In this category, Schottky diodes and varactor diodes are used for frequency multiplication. We analyzed passive devices like resistive diodes (Schottky-barrier diodes) and nonlinear capacitors (varactors). The performance between frequency doubling System using Schottky diode and frequency doubling System using varactor diode is compared. Performance was evaluated in terms of output Voltage (mV), output frequency (MHz) and Output power (dBm). Frequency doubling System using Schottky diode is fast switching and more output voltage and power provides to the load side as compare to frequency doubling System using varactor diode. Input power -4.66 dBm given to frequency doubler using Schottky diode as well as varactor diode system. Output power -13.932 dBm for frequency doubling System using Schottky diode and -28.545 dBm for frequency doubling System using varactor diode is observed. We can use passive frequency doubler using Schottky diode for low power sensing application in wireless communication.
