An application friendly technique to increase the surface area of the ionomer membrane such as Aquivion™ has been
developed. By utilizing existing micro-fabrication technologies, square pillars were fabricated onto glass and silicon
substrates. In combination with a low cost heat press, the glass and silicon stamps were used to successfully hot emboss
micro-features onto the ionomer membrane. Consequently, the surface area of the Aquivion™ membrane was drastically
increased enabling potential improvement of sensing and energy storage technologies. Preliminary results show
successful fabrication of devices with systematic higher surface area and an improved capacitance.
