Abstract (en)
A micro-pump or micro-discharge device comprising piezo-electric means (201) which form part of wall means (201-203) of a liquid reservoir (211), the piezo-electric means (201) being deformable by voltage signals in first and second directions so as respectively to draw liquid into and expel it from the liquid reservoir (211).
