AB  - The paper describes a stretchable, microfabricated power generator that will be 
      attached on the skin and will produce energy based on the movements of the human 
      body. The device was fabricated on a polymeric, elastomeric, 
      poly(dimethylsiloxane) (PDMS) sheet. It consists of a piezoelectric thin film of 
      ZnO sandwiched between two stretchable gold electrodes. An innovative technique 
      was used for the deposition of ZnO thin film on the gold electrode-coated 
      polymeric substrate at low temperatures below 150  degrees C. This is the first attempt 
      to use a uniform film of ZnO, for energy harvesting. The ZnO film had the 
      thickness at the submicron scale and the surface at the centimeter scale. We 
      demonstrated that under a strain of 8% the voltage output from this power 
      generator was equal to 2 V, the power output was equal to 160 muW and the 
      corresponding power density was 1.27 mW/cm(2). This device has great potential 
      for application in power sensors attached on the human body, such as temperature 
      sensors or wearable electrocardiography systems.
