Patent ID: 10770508

Abstract:
An actuator device (AV) including a main body (10) with a base body (10a) and a buildup body (10b) a plurality of actuators which are formed of actuator bodies comprising a piezoelectric or electrostrictive material and actuation electrodes and a printed circuit board (100) which extends in the longitudinal direction (X) of the actuator device (AV) over at least sections of actuator connection coatings, wherein conductive paths thereof are in electrical contact with the actuator connection coatings and wherein in the connection area segment (S0b, S1b, S2b, S3b) of the respective recess (S0, S1, S2, S3) at least in sections a connection layer (V) made of a resin reinforcement material with bismaleimide is disposed such that the connection layer (V) at least in sections contacts side surfaces (AS1, AS2) which respectively delimit a connection area segment (S0b, S1b, S2b, S3b) and which are opposed to each other.
