Design Concept Voltage Regulating Charging Port Batteries Circuit Display Microcontroller Phone App Photo Sensors Bluetooth Watch Buttons Module LEDs for User 3

PCB Design(s) Designed and developed two versions of the PCB board ● Two additional boards were also sent out from Biorasis ● Boards have been tested and we have proved functionality ●

Future Boards and Modularity Smart watch system is modular ● Processor board is independent of measurement board ● Bottom measurement board can be adjusted for signal ●

Screen and Board Overview Processing Micro USB Charging Port LCD Display Measurement Push Button Programming Port Battery Programmer

Photodiode / LED Arrays LED and Photodiode componentes have been attached ● LED array is on a flex circuit, allowing for unconventional fitment ● GaAs filter, will sit between the two arrays ●

Display and Interface Two functioning push buttons and charging port ● Accurate time clock and date ● Animated graphical display of data ● Ability to enter and exit from sleep mode ●

Basic Code Structure 1. Initialize the system. 2. Check if the smartwatch is active: a. If it is active: i. Run the smartwatch tasks. b. If it is not active: i. Enter deep sleep mode. ii. Wake up from deep sleep mode on system interrupt. 3. Repeat from number 2.

Notes on Code/Bluetooth

Watch Enclosure Collaborated with ME team for base layout ● Modeling is being done in Solidworks ● Plan to use higher quality material for final print ●

Enclosure Next Steps Design and print bottom case for complete containment ● Configure push button mechanism ● Bottom viewing window for LED light. ● Ensure fitment of all components, and possibly scale down for aesthetics ●

Timeline Change code to improve functionality and aesthetics: (3/26/18 - ● 4/15/18) Modify enclosure: ● (4/7/18 - 4/20/18) Debug and revise complete watch construction and code: (4/2/18 - ● 4/20/18)
