title: The development of the low profile Liverpool shear transducer.
abstract: The development of a shear transducer, small enough to be worn comfortably under a normal foot, is described, along with a microcomputer controlled data logger. Walks up to 8 s can be recorded and the information downloaded to any IBM compatible computer. Software then allows easy analysis of the peak shear stresses. Calibration curves show the transducers to have a linear response up to 35N and preliminary data from the measurement of shear stresses under the normal foot, and their relationship to vertical pressures, is presented. A patent application (number 9109463.1) has been filed for the device in the United Kingdom.
