DOI: 10.1002/elps.201800357 The cover picture shows vacuum‐driven microfluidic manipulation with a piezoelectric diaphragm micropump for droplet generation. Stepwise changes to peak‐to‐peak voltage applied to the pump during water‐in‐oil droplet creation showed that drive voltage reproducibly controls the droplet generation rate with a rapid system response time (i.e., within <0.5 s after input of a new voltage). The current system can be used not only for droplet production but also for rapid droplet screening.
