The invention relates to a piezoceramic material with a binary mixed system of a alkaline earth perovskite ABO 3 and a bismuth yttrium oxide[...] 3 , wherein at least one element is at least one alkaline-earth metal and B A of main group IV and/or the fourth subgroup of the periodic table is. Also a method is specified for producing a piezoceramic material, comprising the following method steps : a) providing a piezo-ceramic starting composition of the piezoceramic material and b) heat treating the piezoceramic starting composition, wherein the piezoceramic material is produced. With the invention of the piezoceramic material on wet chemical and thus simple thin films can be produced. The material also shows excellent piezoelectric properties in the form of such a thin film. The new material is in particular in MEMS Making (Micro Electro [...] system). The actuator system is used the material but also in, for example, for fuel injection systems or in ultrasonic transducers.
