 Introduction Problem Solution  Constraints Technical Practical  Block Diagram  Approach  Progress  Questions

 On the market today, monitoring armbands cost anywhere from $100 - $200.  Other armbands do not monitor body temperature.  Other products have confusing computer application.  Some products have chest straps.

[2] [3] Mio 0034US – BLK, Energy Pro Plus Chest strap with heart rate zone indicators. $99.95 Polar RCS5 Red Watch Chest strap with calorie counter and is water resistant. $179

 Develop the product to cost less than $100.  Monitor body temperature.  Design computer application to be easy to operate for any age user.  Monitor heart rate with finger strap.

 Technical  Practical

NameDescription Battery LifeThe MyBand Fitness device will run for a minimum of four hours. Capturing DataThe device will capture data at a maximum sample rate of 100 Hz and store the data on separate flash memory of 4 GB. DisplayThe wrist device will display sensor values, clock, and on/off indicator. MeasurementThe product will measure heart rate and body temperature accurately. Physical ParametersThe MyBand Fitness wrist device will fit comfortably around wrist.

TypeNameDescription EconomicCostThe product will cost less than $100. ManufacturabilitySizeThe device will be small enough to wear on user’s wrist.

 To be competitive on the market, must cost less than $100.

 The wrist device will have to be small and weigh less an 1 pound to fit comfortably on the wrist.  Wrist device will have a detachable band.
