• Brainstormed potential ideas:

  • Automated stethoscope
    • compact microphone + enclosure that listens to heart or lungs, provides initial metrics like heartrate on a screen, detects possible issues like murmur or pneumonia by listening
    • opportunities for mobile integration, recording and sending audio to a doctor, tracking heart rate over time
    • opportunities for wearable approach, vest-like form factor
  • Smart scooter
    • add on modules to improve safety/user experience on e-scooter
    • LIDAR/US For automated braking, laser path projection, speed wobbles detection (IMU)
  • Air hockey robot
    • play air hockey with the “computer”
    • opportunity for various difficulty levels, game analytics afterwards/coaching tips on strategies based on game habits (AI powered)

  • Presented the automated stethoscope idea to professors. Seems like a viable idea
    • suggestion: maybe look into EKG/ECG but this would include leads
