Speech title & Synopsis

Smart Medical Monitoring Technology

Healthcare should be easy to access, convenient and stress free. From 2019 to 2022, the world experience tremendous changes due to COVID-19, aside from western medicine, vaccine and other forms of therapy, we have noticed that Chinese Medicine is becoming a popular topic. Chinese medicine practitioner can help people gain access to traditional treatments by using centuries-old healing techniques. In the clinical diagnosis and treatment of traditional Chinese medicine, the temperature change in different areas of a person’s hands can be used as a diagnostic index to the underlying health issues. It is important to have accurate readouts of the temperature at different areas of a hand in real time because the change of temperature also provides information about a person’s health.
Our company developed a more portable, durable hand temperature monitoring device, this novel product has a high-density sensing area and great precision, making it suitable not only for thermal monitoring instruments but also for medical diagnostics. By using our thermal Mat, practitioner can record and download data in just a few steps, analyze and compare data across any number of experiments, analyze patients’ data by factors such as time, rate, and regional variation. Customer can choose between different contact surfaces depending on the application. High resolution for clear thermal image at 2mm per pixel with 0.2 degree Celsius accuracy. It is achieved by pixel sensors fabricated under mature semiconductor manufacturing process. Customizable Temperature range from 5 to 80 Degree Celsius, perfect for checking the surface condition of a palm or any other product. Area up to 20cmX20cm with 1000 measurement points, the 2 Hz response time to temperature changes ensures measurements are as accurate as possible. Customizable size and high-density IOT data allow us to investigate the opportunity and significance hidden beneath the thermal flux of human body.
