Abstract |
Stretchable electronics are very important and attractive field for the next-generation devices like electronic skin, sensors and displays. To use these devices, human interaction is also very important part. We propose highly stretchable and pressure responsive electrochemiluminescence (ECL) display device, using ECL gels consisting poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-co-HFP), 1-Ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imdie ([EMI][TFSI]), and Tris(2,2'-bipyridine)ruthenium(ll) hexafluorophosphate (Ru(bpy)3(PF6)2). Device is all printed by inkjet printer which are polydimethylsiloxane (PDMS) (as spacer) and ECL gel (as active layer) on the stretchable electrode. The device only emits light when human touch the PDMS spacer to contact ECL gel and the electrode. The device can be stretch up to 50% biaxial with negligible damage. Total thickness is very thin that is about 300~400μm. This device has high response time and resolution (up to 100um for one pixel), which can detect the touch stimulation and give human interaction by it's shape directly and fast. |
