Abstract
A distance sensor () for estimating a distance to a surface (OS) of an object (O), the distance sensor including a micro electric mechanical system (MEMS) (), a detection means () and a processing device (). The MEMS comprises a MEMS device () having a surface (), denoted as MEMS sensor surface, to be arranged opposite the surface (OS) of said object (O) and a MEMS driver () for generating an ac driving signal to cause the MEMS sensor surface () to vibrate. The detection means () is to determine a value of a property of a dynamic behavior of the MEMS () and the processing device () is to estimate an average distance (h) as a measured distance (D) between the MEMS sensor surface () and the surface (Os) of the object (O) based on the determined value for said property.
