      abstract     = {Due to their tendency to form ionic states, transition
                      metal oxides and especially SrTiO3 exhibit extraordinary
                      ferroelectric properties. However, they typically exhibit
                      these extraordinary properties close to the ferroelectric
                      phase transition temperature, which usually deviates
                      significantly room temperature. The question arises as to
                      whether, and how, these extraordinary properties can be
                      utilized. It is therefore of major interest to engineer
                      these materials to fully exploit and understand their
                      potential, and to make them suitable or more suitable for
                      various applications.One method of engineering the
                      properties of these materials is to use mechanical strain.
                      In particular, epitaxial strain, which is automatically
                      generated in epitaxial films grown on lattice-mismatched
                      substrates, allows crystalline oxides to be elastically
                      strained up to percent levels. Under such strain, the
                      properties of the transition metal oxides can be altered
                      significantly.In this article, we review the use of
                      epitaxial strain to modify the ferroelectric, electronic,
                      and structural properties of SrTiO3. We discuss how the
                      ferroelectric properties can be tuned systematically by
                      strain. This includes the tuning of the ferroelectric
                      transition temperature, permittivity, and the type of
                      ferroelectricity. We demonstrate that these epitaxially
                      strained films typically represent textbook-like relaxor
                      ferroelectrics and are highly tunable. Furthermore, we show
                      that even the conductance of the nominally insulating
                      material can be modified by epitaxial strain. With adequate
                      strain, SrTiO3 not only becomes semiconductor-like, it also
                      exhibits an “electronic plasticity”, which is of
                      interest for applications ranging from memristor to
                      neuromorphic devices such as artificial synapses
                      (e-synapses). The examples discussed demonstrate how elastic
                      epitaxial strain represents an exciting option for
                      engineering and fine-tuning the properties of SrTiO3 thin
                      films.},
