In the area of healthcare, an Internet of Medical Things (IoMT), i.e., interconnected, networked medical devices, will offer new avenues of diagnosis, personalized therapy, epidemiology, and healthcare services in a timely, sustainable, individualized, and cost-effective mode of delivery. Today, smartphone technology has a growing and pervasive influence on our daily life. Especially, with the rapid development of microfluidics technology, the incorporation of microfluidics technology with smartphone-based detection technology will create a new paradigm shift towards affordable, mobile, personalized, health monitoring. In this talk, I will introduce our superhydrophobic plasma separator, molecular diagnostic chip, smart connected cup (SCC) and their applications in disease diagnostics (i.e., HIV, ZIKV, HPV virus) at the point of care.
