Abstract
A probe for position determining apparatus has a probe body () and a workpiece-contacting stylus (). A strain sensitive structure connects the probe body and the stylus, and includes bendable members (). The bendable members have an asymmetric cross-section, e.g. 'T' shaped. A strain gauge () is mounted to the stem of the 'T' to detect the bending caused when the stylus contacts a workpiece. This enables the strain sensitive structure to be both robust and sensitive to the bending.
