Rapid prototyping of microchannels with bell‐shaped (as opposed to rectangular) cross‐sections (see Figure) is reported. These microchannels are ideal for deformation‐based microfluidic valving using piezoelectric vertical actuator arrays in refreshable Braille displays. The fabrication method is based on diffused backlight exposure with a transilluminator and is cost and time efficient.
