Saurabh and the GraphWear team have a next level wearable technology product. Unlike other companies who purchased sensors from third parties they decided to invent their own form of Graphene to collect unique and valuable health biometrics. I am confident that this team will continue to succeed and become the number one sweat analysis company.

There a dozens of health/wearable companies and dozens of graphene companies. What makes GraphWear unique is the proprietary functionalized graphene sensor that enables the continuous measurement of previously unmeasurable quantities, non-invasively. Through the continuous measurement of these new quantities, be it electrolyte levels, glucose levels, or other, GraphWear can enable new understanding of human health issues, making GraphWear an enabling sensor platform but also an enabling data platform.

GraphWear is not just another wearable company.

I worked with the GraphWear team for 4 months while they were in for acceleration at Dreamit Health. Both founders are very focused, smart, driven, and are building a great platform technology with vast possibilities.

I believe the solution that GraphWear has produced is a very timely and innovative solution. Today there exists no usable data about the state of a human body that is both non-invasive and readily available to the user. With the advent of a sweat based solution such as this the possibilities as well as applications are many fold. Both founders of this company possess exactly the right attitude and drive to make a solution such as this possible. Having worked in nanotechnology for >10 years now I see their approach as one of the first great uses of nanoscale carbon for detection / diagnostics that have been conceived. Please don't hesitate to contact me with any follow on questions.

Non-invasive biomonitoring
Philadelphia, Pennsylvania, United States United States

GraphWear has developed a real-time dehydration, glucose, and lactic acid monitor without the need for blood or urine. Our patch analyzes your sweat in a wearable form factor which pairs with your smartphone and gives actionable metrics. This is possible because of the high sensitivity of graphene, a cutting edge nanoscale material.

Company description

We are making a wearable sensor that analyzes your body non-invasively. Your body is constantly sending out biochemical information from your saliva, breath, sweat, and even earwax. We are starting with sweat analysis. Sweat is diluted and ultrafiltered  blood. When your body tries to cool off, your brain sends a signal to your blood to push out water. This water comes out as sweat through your sweat ducts. Sweat brings along with it trace concentrations of electrolytes, glucose, lactic acid, and an array of proteins that are reflective of your health.  By harnessing this information, we are opening a whole new door to non-invasive biomonitoring.

Our solution is possible because of the sensitivity of the Nobel Prize winning nanoscale material graphene. Via a patent pending process developed by the founders during their thesis, we can create a graphene device that has almost ideal properties which is low cost, easy to manufacture, and highly scalable.

Business model

Our cost of goods is $10.10 per device at scale. This breaks down as follows:

i. Cost of sensor: $1.00

ii. Cost of Bluetooth chip (Rigado BMD-200): $6

iii. Cost of adhesive and sweat collection system: $0.10

iv. Cost of battery: $1.00

v. Cost of packaging and design: $2

Our sales model is a razor and blade model, where the Bluetooth chip, the sensor, and the battery cost $99.99 and can be used repeatedly, whereas the adhesive with embedded sweat collection system need to be replaced every use at a cost of $0.50 per patch. These numbers were obtained by surveying over 3 dozen athletes and asking what they believe such a device should cost. With over 20% of the survey participant’s answer >$200 and 80% in the >$100 range, we believe our customer will be willing to pay this price for our device.


Competitive advantage

Direct and Indirect Competitors

There is no product currently on the market that can analyze sweat and give information about dehydration, glucose, lactic acid, or any other vitals. This gives us the unique opportunity to be one of the first to market.

Emerging Competitors

There are a few different companies working on a hydration sensor, as well as a few trying develop a glucose and lactic acid monitor. However, none are using graphene, which is the ideal molecular sensor. Since graphene is only one atom thick, every single carbon atom is exposed to the surface. This makes interactions with other molecules very specific, thus allowing a high degree of sensitivity and selectivity. We are the only company to be using graphene for monitoring glucose, electrolytes, and lactic acid. Our low cost also gives us a highly competetive price.
