Considering the human finger is very sensitive to texture perhaps there is a material that change its texture in response to voltage?

  Why not just use mechanically decoupled pins that vibrate with a smartphone vibration motor? You don't need texture if the thing vibrates.

    Cost and noise would make that extremely unpractical.

      As opposed to the low cost texture changing material proposed? If I had to do this I'd probably look into PCB-based solenoids with compliant mechanisms. But there are already people working on that.
