近年来，磁电传感器在医学上的应用越来越重要。在几种传感器类型中，微机电磁场传感器是一种很有前途的选择，因为它们可以以非常小的方式制造并且可以在室温下工作。在此贡献中，我们提出了一种新的读出方案，该方案同时使用单个传感器的多种机械模式的幅度和相位信息。传感器基于delta-E效应。将提取的所有信息进行优化组合，以获得具有最大信噪比的传感器输出信号。最初的测量显示出非常有希望的结果。
Recently, magnetoelectric sensors have gained importance in medical applications. Among several sensor types microelectromechanical magnetic field sensors are a promising option since they can be manufactured in a very small fashion and can operate at room temperature. In this contribution we present a new readout scheme for such sensors that simultaneously uses amplitude and phase information of a multitude of mechanical modes of a single sensor. The sensors are based on the delta-E effect. All extracted information is optimally combined in order to get a sensor output signal with maximum signal-to-noise ratio (SNR). First measurements have shown very promising results.
