Abstract: There is an essential limitation that only surface principal stress sum variation (Δ(σ1+σ2)) can be measured as physical quantity by a thermoelastic stress measurement technique, and furthermore respective principal stress components are unknown, and pure shearing stress acting on an object cannot be measured because it causes no temperature variation. Thus, in the present invention, when stress state of the object is measured, not only the thermoelastic stress measurement but also stress measurement (mechanoluminescence measurement) using a mechanoluminescence material is used in combination. Consequently, stress can be measured in detail; for example, principal stress component values (σ1 and ρ2) can be known while exceeding the principle limitation of the thermoelastic stress measurement technique.

Abstract: A force and torque converter is provided that senses force and torque applied to the device. The converter includes a base, a grip, resilient connection members that extend radially and coplanarly from a central hub, located within the grip, and that connect to the grip, and sensing mechanisms to sense the displacement of the connection members. The displacements are resolved to determine the force and torque that is applied to the device, with respect to a Cartesian coordinate system.
