US research and development of biosensors reveals sweat that you don't know

It is well known that people sweat when they exercise to a certain extent, and sweat can help the body cool down. But beyond that, sweat contains a lot of little-known useful data.

Founded by Joshua Windmiller and Jared Tangney, Electrozyme is a company that focuses on sweat data analysis. The company has developed a wristband with a built-in biosensor. It can be in contact with the user's skin surface and can read chemical information from its sweat, and then show how the user's body reacts after strenuous exercise.

It is known that Electrozyme's biosensor can quickly analyze the chemical composition of sweat and provide real-time feedback on hydration, fluid loss and electrolyte balance. Wade Miller recently showed the relevant technology at the "Internet of Things Summit" held in San Francisco. He said that they are currently negotiating with a number of vendors to integrate the biosensor into the existing fitness tracker and Others. In wearable devices.

Electrozyme's goal is to go beyond the current wearable devices on the market that only provide some regular sign data. "At present, most of the wearable devices measure similar physical signs, such as speed, heart rate and walking steps," Wade Miller said. "The limitations of this information are actually very strong."

Let's take a look at how this biosensor wristband works. It can be used with a third-party fitness tracker, the wrist strap is loaded on the back of the tracker, so it can touch the wearer's skin, and the embedded electrochemical sensor will detect various biological indicators in the sweat, including electrolytes. , sodium, lactic acid, protein, etc., to obtain biometric data of the user's physical condition. At the same time, Electrozyme's algorithm software can analyze these metrics data and then provide users with some personalized advice on continuous exercise.

Electrozyme plans to use print sensor technology to make this wristband, so its manufacturing cost is very low and it is disposable. In other words, if the wristband that is soaked in sweat is disgusting after the user moves, he can throw it directly into the trash can.

Electrozyme hopes to use the sensor to tell the user when it needs to replenish moisture, how much to drink, whether to drink water or drink sports drinks at the initial stage, and it will generate too much when the user may have a heat stroke or other means. Alerts are given to the heat; in addition, Wade Miller and Tigney are also improving the sensor around preventing the user from cramping. In the future, they also plan to add more functions to the product. In addition to the existing electrolyte balance and dehydration measurements, it is expected to measure the user's muscle fatigue, physical exertion level, respiratory and skin pH and other more detailed creatures in the future. Sign data.

Although Wade Miller and Tangley founded Electrozyme in 2012, Wade Miller is a postdoctoral in electrical engineering at the University of California, San Diego. He has worked in the field of electrochemical sensors for more than four years. So far, Electrozyme's sensor platform has been field tested by hundreds of strategic partners from Fortune 100. According to the introduction of the two co-founders, most of the participants are very interested in this platform.

Currently, they plan to release the license interface for the Electrozyme platform by mid-2015, and the device incorporating the sensor technology will be available in 2015, and the above wristband products will only be connected to devices approved by the Electrozyme platform. .
