AB  - In response to the extensive utilization of ionic circuits, including in 
      iontronics and wearable devices, a new method for fabricating a hydrogel-based 
      ionic circuit on a polydimethylsiloxane (PDMS) microchip is reported. Prolonged 
      UV/ozone oxidation combined with proper surface functionalizations and a novel 
      microchip bonding method using thiol-epoxy click reaction enable the robust 
      attachment of the photopolymerized hydrogel to the microchannel surface for 
      eventual operation in electrolytes as an ionic circuit. The stretchable ionic 
      diode constructed on the PDMS microchip shows a superior rectification ratio even 
      under tensile stress and long-term storage stability. Furthermore, the 
      combination of the ionic circuit and unique material properties of PDMS allows us 
      to maximize the versatility and diversify the functionalities of the iontronic 
      device, as demonstrated in a pressure-driven ionic switch and chip-integrated 
      ionic regulator. Its iontronic signal transmission mimicking the excitatory and 
      inhibitory synapses also evinces the potential of the hydrogel-based iontronics 
      on the PDMS microchip as developed toward an aqueous neuromimetic information 
      processor while opening up new opportunities for various bioinspired 
      applications.
