Brain-Controlled Robotic Hand with Adaptive AI & Haptic Feedback

Granted Indian Registered Design No. 504827-001 for adaptive neural-interfaced bionics

A brain-interfaced bionic hand architecture combining adaptive artificial intelligence with micro-actuated haptic feedback, granted registered design protection by the Patent Office, Government of India.

Problem: Traditional myoelectric prosthetics suffer from high rejection rates due to lack of tactile feedback, high latency, and rigid pre-programmed grasp patterns that fail on everyday asymmetrical objects.
Approach: Engineered an anthropomorphic 5-finger articulated mechanical structure coupled with closed-loop adaptive grip pressure regulation and cutaneous haptic feedback actuators to inform the user of grasp contact and slip.

Comparative Study of 6T and 8T SRAM Cells under Low-Voltage Operation

Cadence Virtuoso transistor-level simulation evaluating stability margins and leakage at sub-1V VDD

In-depth semiconductor research comparing standard 6T and decoupled 8T static RAM cell architectures under aggressive supply-voltage scaling, analyzing Static Noise Margin (SNM), read-disturb vulnerabilities, and leakage power.

Problem: As supply voltages scale below 0.8V to minimize active power in IoT and edge hardware, standard 6T SRAM cells encounter dramatic degradation in Read Static Noise Margin (RSNM) due to voltage-divider action at storage nodes, leading to destructive read upsets.
Approach: Built complete transistor-level schematic topologies in Cadence Virtuoso. Simulated DC butterfly curves to extract Hold SNM, Read SNM, and Write Trip Voltage (WTV) across varying VDD supply levels, evaluating how the decoupled read buffer of the 8T topology alleviates read-disturb.

RLC Frequency Response Simulator & Automated SPICE Netlist Generator

Full-stack circuit analysis platform with real-time Bode plot visualization and transient solver

A full-stack computer-aided engineering platform for series and parallel RLC network simulation, calculating resonance, quality factor (Q), bandwidth, and generating automated SPICE netlists with real-time Bode plots.

Problem: Undergraduate engineers and hardware hobbyists frequently struggle to visualize how passive component tolerances, parasitic resistance, and damping factors distort high-frequency circuit response before hardware fabrication.
Approach: Engineered mathematical state equations in Python/NumPy exposed through a RESTful Flask API. Built an interactive browser frontend that renders real-time logarithmic magnitude and phase Bode plots, sensitivity curves, and automated downloadable SPICE netlists.

Smart Asthma Guardian — Wearable Healthcare & Environmental Monitoring

Arduino UNO R4 wearable monitoring particulate air quality and patient vitals with predictive alerting

A wearable preventive healthcare system continuously monitoring ambient air quality (particulate matter PM2.5/PM10) and vital biometric parameters to warn respiratory patients prior to triggering hazardous asthma attacks.

Problem: Asthma patients and individuals with chronic respiratory conditions are frequently exposed to localized micro-climate pollution spikes without warning until severe bronchospasms occur.
Approach: Interfaced optical dust sensors, temperature, and humidity sensors with an Arduino UNO R4 WiFi, deploying edge thresholds that alert the wearer through audio-visual and companion mobile notifications when environmental hazard indexes cross personalized limits.
