1 Design Concept & Technical Requirements
Chest Component

2 Required Functionality
Determines heart rate continuously Records EKG statistics Determines if user suffers a severe impact e.g. falls, vehicle collisions Communicates information to wrist component Central processing unit interprets data and determines if there is need for medical assistance

3 Technical Requirements
Ideal weight range g About the weight of a men’s shirt Ideal power usage 4-6W The same usage as an iPhone 4G With an equivalent battery, should only require charging at night No more than 2cm thick Will be nearly invisible underneath a sweater or a loose shirt Under $100 to make

4 Exterior Design Optional Shoulder Supports Adjustable Elastic Band
Primary Electronic Components in Plastic Casing

5 Necessary Components EKG Sensors Accelerometer Thermometer
CPU, Communications iPhone CPU, Components

6 Power, Weight Breakdown
EKG - approx. 50mW Accelerometer < 25mW Processing (at 1GHz) - approx. 4W Weight g EKG - approx. 17g Accelerometer < 1g Thermometer < 1g Processor and wireless transmitter < 50g Plastic casing, straps < 100g Battery < 100g Research paper on low-cost, low-weight EKG sensors and tech:

7 Cost Breakdown EKG sensors and module Wireless technology, processor
Most expensive component and based on current retail costs can run up to $75 to produce. Maybe have redundancies with processor than can be reduced Wireless technology, processor The costs of these components have all been driven down due to mass manufacturing in smart phones. On one chip, these will probably cost only $30 to mass produce. Accelerometer, Thermometer Less than $0.50 to buy Straps and casing Less than $2 to make/ buy EKG Sales (pricing info): iPhone information:

8 Risks Cost The biggest risk to this project is the cost of the components The EKG equipment is extremely expensive Further research may be required to eliminate cost by reducing redundancy with central processor Processor Ideally, we will be able to use components like wireless technology, accelerometers, flash memory and CPU that have been driven down in cost by the production of smart phones Power Integration of components may require more power than anticipated Battery may end up being bulky, heavy or expensive
