Measurement bench for the study of the behavior rheological of soft materials, in particular of delivery or physiological tissue

摘要

Measuring apparatus which applies tension and compression to a sample of soft material, is new. The apparatus has a computer controlled actuator mounted on a fixed support. A piston of the actuator is attached to a proximal end of a carriage. The opposite ends of the sample are attached to the distal end of the carriage and a force sensor mounted on the support. Measuring apparatus which applies tension and compression to a sample of soft material, is new. The apparatus has a computer controlled actuator mounted on a fixed support. A piston of the actuator is attached to a proximal end of a carriage. The opposite ends of the sample are attached to the distal end of the carriage and a force sensor mounted on the support. A signal processor characterizes the material in terms of the force detected by the sensor relative to the linear displacement of the piston. The sample is immersed in a temperature controlled enclosure. The apparatus may be arranged vertically with the sample located below both the actuator and the sensor.
