                    Concluding Remarks
   • Global aging population, the increase in
     population with chronic diseases and
     awareness to healthcare lead to high global
     demand in ubiquitous healthcare electronics.
   • China announced its “Healthy China 2020
     Plan” (醫療電子下鄉) which create huge
                                 ,p
     market demand in low-cost, portable and
     easy-to-use HE in China.
   • Lack of core technologies for the realization
      f     t ff ti     low-power, easy-to-use and
     of cost-effective, l               t         d
     reliable UHE products in the market.
   • Lack of UHE-related certification knowledge
     and expertise.
