Pressure sensors detecting mechanical deformation are one of key components for wearable ionotronics. In this study, we propose an effective route to tune ion gel characteristics by adjusting pendant groups of ionic liquids. We created film-type ion gels very conveniently by one-pot photopolymerization. The ion gel films were carefully characterized and optimized. The ionotronic pressure sensors based on the optimized gels provided high sensitivity (~3.02kPa-1), wide detection range (~100 kPa), and excellent durability (~6,000 cycles). Their practicality was evaluated by fabricating unit cell arrays for sensory applications.
