How MiClimate works
MiClimate is a 12V battery operated device that is small, weighs less than 2 pounds, and generates cool and warm air. The air flow based system assists the thermoregulatory system of the body. Sensors and biofeedback enables temperature control as desired for temperature management and precision treatments. Similar to a central air conditioning at home, the conditioned air is transported through a duct around the waist. Air is released at the waist level under shirt (no specific shirt required), which then distributes conditioned air over the torso, exiting around the neck.
Heat Transfer Schematic
Heat Transfer: As air flows over skin, it picks up sweat and carries latent heat of evaporation; cooling further and assisting thermoregulatory system of the body. Combination of evaporative cooling of sweat and cooler air provides comfort to the body. Similarly, warm air flow provides more effective heat transfer at the skin surface giving higher level of comfort compared to heated jackets. A smart control system with biofeedback and machine learning would automate the system to adapt to the user lifestyle.
The core technology behind the device is century old Peltier thermoelectric. Over the years technology has matured to be suitable for lower power and smaller form factor hardware. The effective heat transfer components are key to achieving smaller form factor and design. As shown in, heat is extracted from one air flow stream and transferred to the other stream, causing the first stream to be cooler than as entered. Entire integrated system has been designed, after many simulations and trial and error, to minimize pressure drop so the conditioned air is effectively distributed over the torso (MiClimate IP).
Working with the doctors and researchers we will integrate wearable sensors in the belt which will communicate with the AC unit. Biofeedback in conjunction with machine learning will control the air conditioning system to the comfort level of the patient. Multiple sensors are envisioned to gather all possible data to develop powerful analytics to aid doctors and researchers to develop precision treatment. The system will seamlessly integrate with smart phones and to cloud computing enabling advanced analytics. Once connected with the smart phone, doctors could monitor patients and their progress. In some cases friends, relatives or care takers may want to remotely monitor the health of a patient – the same technology will make such monitoring and thermal treatment possible.
