A resonator micro-electronic inertial sensor, preferably a micro-electromechanical system (MEMS) sensor (e.g. a gyro), for detecting linear accelerations and rotation rates in more than one axis comprises: €¢ a proof-mass system (21.1, ..., 21.4) flexibly suspended above a substrate for performing a rotational in-plane vibration about a central axis (24,) €¢ a drive electrode system (D1, ..., D4) for driving the proof-mass system (21.1, ..., 21.4) to perform said rotational in-plane vibration, €¢ and a sensing electrode system (S1, ..., S8) connected to the proof-mass system (21.1, ..., 21.4) for detecting linear accelerations or rotation rates in more than one axis. Said proof-mass system (21.1, ..., 21.4) has more than two proof-mass elements flexibly coupled (25.1a, 25.1 b) to each other. Each proof-mass element (21.1, 21.2) is directly and flexibly connected (23.1, 25.1a, 25.1 b) to an anchor structure (22) on the substrate (32). The proof-mass elements (21.1, ..., 21.4) are preferably arranged in a ring-shaped configuration between an inner and an outer radius (R1, R2) with respect to the central axis (24).
