Measuring apparatus characterizing soft biomaterials, e.g. tissue in terms of force detected by sensor relative to linear displacement of sample applied by piston of computer controlled actuator

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.
