      Organic Electrochemical Transistor.

AB  - Patterning elastomers is an essential process for the application of elastomers 
      to stretchable bioelectric devices. In general, replication of a mold and laser 
      ablation are used for patterning elastomers. However, these methods are 
      inefficient and time consuming due to complex patterning procedures and a 
      heat-induced curing mechanism. In this work, we developed a photopatternable 
      elastomer called thiol-ene cross-linked poly(dimethylsiloxane) (TC-PDMS). TC-PDMS 
      showed high-resolution patternability ( approximately 100 mum) through a direct patterning 
      process. It also had high stretchability ( approximately 140%) and low Young's modulus ( approximately 2.9 
      MPa) similar to conventional PDMS. To demonstrate its practicability in 
      stretchable bioelectric devices, TC-PDMS was applied to a passivation layer of an 
      intrinsically stretchable organic electrochemical transistor (OECT), which showed 
      a low leakage current ( approximately 20 muA) and a high transconductance (0.432 mS) at high 
      strain (60%). The stretchable OECT was able to record electrocardiographic (ECG) 
      signals from human skin, and the measured ECG signals exhibited a high 
      signal-to-noise ratio of 12.2 dB.
