Smart Patch for Your Health

Tiny, Waterproof Patch with Sweat Based Sensors

Spots Health Conditions Real-Time
A patch has been developed by bioengineers at Northwestern University that reads your sweat and spots medical conditions.  The sweat based sensor provides real-time information on the wearer's levels of chloride, glucose and lactate, sweat rate and pH. The device lets you know if you are dehydrated, lack oxygen, dangerously low on electro-lights, have diabetes or cystic fibrosis.

Next Generation Health Tracker
Today's fitness trackers gather mostly mechanical metrics.  A new generation of devices are being developed to access the person's underlying medical conditions.  Northwestern's device is a leading example.

Personalized Health Care
Northwestern's device is a personalized approach to fitness and health.  It is battery free, wireless and uses sensors and colorimetrics to provide results.  To put it simply, the patch has tiny holes where the sweat goes in and moves through microchannels & valves the width of a human hair.  The sweat ends up in tiny reservoirs with sensors that react to chemicals in the sweat.  It's highly advanced technology.  The sweat-based sensors are waterproof, mold to the body and can even be used by swimmers. The readouts can display on a smart phone or even a treadmill.
