ComponentsFlex Sensor – Input for posture
Tilt Switch – Input for pedometer
Arduino – Processor
Vibrating Motor – Output for posture
LCD Readout – Output for pedometer
Components – Flex SensorUni-directional Bend Sensor
Resistance decreases as device is bentOften connected in series with a
capacitor to influence timing
Available in multiple ohm ratingsNo selection yet
Components – Tilt SwitchMercury switch influenced by motion
and gravity
Many practical applicationsRoll sensingFall alarmingFuzes
Components – ArduinoDIY Microcontroller
14 digital I/O pins, 6 analog I/O pins, 16 MHz, 5 Volt operating voltage
USB, AC adaptor, or battery operated
“Shields” for easy compatibility
Easy to use softwareSimilar to Java
Components – Vibration MotorFound in all cell phones, game
controllers, etc.
2 – 3.6V operating range
Plan to integrate 2 – 4 of these for cummerbund
Components – LCD Readout Only Arduino shield we will use
Keypad for manual reset
16x2 LCD white character, blue backlight
Only uses 2 pins of the microcontroller
Piecing It TogetherFive components all need to work
independently of each other, yet all are integrated Also integrated with the human body
Arduino is the right tool, yet we’ve never used a microcontroller
SolutionStart earlyStay ahead of schedule
Decisions and RisksTo MOSIS or not to MOSIS?
Microcontroller suited our needs bestSacrificed experience for easy integration
and customization
Did we take on too much?Added functionality of the pedometer
Adds an additional interaction with the human body and additional components
Bigger budgetBroader audience outweighs extra
potential for failure
ScheduleDocumentation and Presentations
Design (Nov. 2)Final Report (Mar. 22)Founder’s Day (Apr. 9)
First integration of flex sensor and vibration motors (Nov. 14)
