SUMMARY:Green flexible electronics and the potential impact to our soc
 iety and environment\, Chaos & Complex Systems Seminar\, Jack Zhenqian
 g\, UW Department of Electrical and Computer Engineering
DESCRIPTION:Electronics industry helps sustain the GDP growth in devel
 oped countries. However\, consumer electronics\, such as cell phones\,
  tablets and other portable electronic devices\, are made with the con
 sumption of large amount of precious non-renewable natural resources\,
  such as indium and gallium etc. These consumer electronics are freque
 ntly upgraded or discarded\, leading to serious environmental contamin
 ation. Thus\, electronic systems consuming the minimum amount of natur
 al resource that could also naturally degrade over a period of time ar
 e desirable which can potentially reduce the accumulation of persisten
 t electronic waste disposed of daily. We demonstrate high performance 
 flexible microwave and digital electronics that consume the smallest a
 mount of natural resources on a biobased\, biodegradable and microwave
  compatible cellulose nanofibril (CNF) paper\, along with degradation 
 of these electronic systems. With rapid technological advances leading
  to significant decrease in the lifetime of consumer electronics\, suc
 h green chip technology with high-performance would be ideal replaceme
 nt for future electronic chips where nonrenewable resources are consum
 ed.
