According to the Daily Mail, a team of professors from Northwestern University, John A. Rogers, developed an ultra-thin “skin patch†that monitors the metabolites and electrolytes produced by sweat during exercise. The user's physical health and synchronization of the data to the 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, and 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 index, which react with certain biochemicals in the sweat, and these reactions 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. †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.
Compact Solar Water Heater is a cost-effective system for residential hot water
application. This system is designed according to thermosiphon principle and
operating with proportion difference between cold and hot water. The water
heated by Vacuum Tubes is held in the stainless steel storage tank where the
insulation preserves the heat.
The
compact solar water heater uses the sun to heat the working fluid (mostly
water) in the vacuum tubes. The Solar Collector absorbs solar radiation, and
converts the sunlight to heat and transfer it to the water. The heated water
naturally rises through the solar collector into the water tank where the
cooler water at the bottom of the tank is forced out and descends to the bottom
of the collector (thermosiphon circulation). The circulation will be
interrupted when there is no solar radiation.
