Digital Soil Core
Digital Soil Core for Precision Agriculture
The Digital Soil Core was developed as a robust tool for real-time soil analysis in agricultural and environmental applications. Designed to measure soil properties at various depths, this device integrates multiple sensors to provide farmers and researchers with precise, actionable data on soil conditions.
Key Design Features:
Multi-Sensor Array: Equipped with sensors to measure soil moisture, conductivity, and temperature at different depths, enabling detailed profiling of soil conditions.
Rugged Construction: Built to withstand field conditions, with a modular design that allows for easy maintenance and adaptability to varying soil types.
Data Transmission: Integrated wireless connectivity for real-time data collection, providing users with instant insights and reducing the need for manual sampling.
Outcome: The DSC offers a reliable, user-friendly solution for improving agricultural productivity and environmental monitoring by delivering precise soil data that supports informed decision-making.
Smart Knee Brace for ACL Recovery
Smart Knee Brace for ACL Recovery
To enhance post-ACL surgery recovery, I collaborated with electrical engineering and medical students to create a smart knee brace equipped with sensors for real-time tracking of muscle activation and knee movement. The design evolved from a bulky, angle-restrictive brace to a lightweight, comfortable model based on feedback from patients and healthcare providers.
Key Design Features:
Modular Sensor System: Integrated accelerometers, angle sensors, and detachable EMG sensors to monitor key recovery metrics.
Custom Hinge: Angled and offset to align with the knee’s natural rotation, ensuring accurate joint movement measurement.
Non-Intrusive Data Collection: Compact electronics embedded in a brace sock for patient comfort and ease of use.
Outcome: The final design provided valuable feedback to patients and physicians, delivering insights into recovery progress without sacrificing comfort.
Generation 1
Original concept was based around a rigid brace that restricts the flexion and extension of the knee joint. This restrictive brace was combined with EMG sensors placed around the knee to monitor muscle activity during physical therapy.
Generation 2
A new custom circuit board and three new sensors were added to this version. Two accelerometers, each placed near the central point of the femur and tibia respectively, and a precision potentiometer coupled to the hinge. In addition, the battery was relocated and electronics rearranged to slim the design.
Generation 3
The final prototype was sewn to a compression sleeve typical for ACL post operative recovery to minimize the impace on the patient. The thin EMG sensors were placed inside the compression sleeve to ensure constant contact with the skin.
Independent Mobility Platform
Open Source Adaptable Design
Independent Mobility Platform for Children with Mobility Impairments
As part of a SEED Senior Design project, I led a team to create an innovative mobility platform aimed at providing young children with enhanced independence and adaptability. The initial concept involved a powered attachment for wheelchairs, but after multiple iterations, we developed a solution that maintained wheelchair height while reducing load requirements.
Key Design Features:
Adjustable Roller System: Designed to fit a variety of wheelchair sizes, enabling ease of customization and secure attachment.
Two-Wheel Powertrain with Castors: Optimized for terrain adaptability, allowing children to navigate diverse environments safely.
Custom Control System: Collaborated with an electrical engineer to implement a 5-degree-of-freedom joystick, ensuring smooth acceleration and deceleration.
Outcome: Successfully tested with a 5-year-old user, this platform provided a safe, intuitive solution for young children to gain independence. The project received the SEED Innovative Solution Award.
