Inclusions

 Flexible passive inclusions can spontaneously curve and move due to unbalanced pressures:

 

An asymmetric inclusion will experience a force,

     

balanced by counter-flow current flow of active particles:

Asymmetric inclusion acts as pump; conservation of current leads to long-range modulations of active particle density
