Cholesterol Bio Sensors: getter better fast
These slides use concepts from my (Jeff Funk) course entitled analyzing hi-tech opportunities to analyze the increasing economic feasibility of bio-sensors for measuring cholesterol in humans. Bio-sensors detect the level of cholesterol (and other biological materials) using enzymes, matrices, and transducers. The enzymes, which are held in a matrix, react with the cholesterol and an electric signal is produced from an amperometric transducer. Improvements in sensitivity, response time, shelf life, detection limit, and reusability have been achieved through creating more appropriate biological materials for the enzymes, matrices, and transducers.

This document discusses the role of enzymes in biosensors. It begins by defining a biosensor as a device that incorporates a bioactive material with a transducing element to detect the concentration or activity of an analyte. Enzymes are well-suited for use in biosensors due to their high selectivity and catalytic activity. An enzyme-based biosensor works by immobilizing an enzyme on an electrode surface - the analyte interacts with and is converted by the enzyme, and this reaction can then be detected electrochemically. Common examples are glucose oxidase in glucose biosensors and urease in urea biosensors.

Embedded machine learning-based road conditions and driving behavior monitoring
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.
