The team of Professor John A. Rogers of Northwestern University has developed an ultra-thin "skin patch" that monitors the user's health and data based on the metabolites and electrolytes produced by the user's sweat during exercise. Sync to your smartphone in real time. However, this coin-sized skin patch itself does not require a power source and is only effective for a few hours.
Human sweat contains a wealth of physiological information that opens up new opportunities for bio-worn devices. However, since the sweating process of the human body is complicated and it is necessary to extract effective information related to the skin from various aspects, it is not easy to complete the research. Professor John A. Rogers has been working on bio-wearable electronic devices for many years. He has finally launched this ultra-thin patch that can read health information from sweat, and recently published the research and development results. Science TranslaTIonal Medicine, in the journal.
As the user moves against the patch, the resulting sweat passes through the microfluidic channel through the entire device and into four separate circular "reservoirs". Each "storage" contains different reagents that represent glucose, chloride, lactate, and pH, which react with certain biochemicals in the sweat that make each reservoir The color changes. Since the user has downloaded a special APP on the mobile phone, the software will determine the level of various indicators in the human body after analyzing the color change of the storage. In this way, the user can obtain information such as his sweat rate and total sweat loss by using the reader on the mobile phone.
In an interview, Professor John A. Rogers said, “For example, when you are doing some simple fitness activities, once the dehydration occurs, the phone will signal, and you should add electrolytes. â€
When you are sweating, this skin patch can read your sweat and monitor health information.
More importantly, Professor Rogers hopes that the device can be used in a wider range of areas, such as military training, and even in the future to help people with certain diseases, such as real-time monitoring of diabetes patients.
