Evaluating the Viscoelastic Behavior of Elastomers Using a Piezoelectric Tactile Sensor and an Optimization Approach

Elastomers, polymers, and human tissues are well-known viscoelastic materials whose behavior are hard to grasp. Several mathematical models, being linear and nonlinear, have been proposed to describe the elastic and viscous properties of viscoelastic materials. In this paper, we aim to characterize the dynamic properties of silicon rubber viscoelastic material with different mixing ratios. To this end, an experimental setup using a piezoelectric cantilever was used to apply force to the viscoelastic specimens, and an eddy current sensor was used to measure the displacement. We used the Standard Linear Solid (SLS) model and the hysteresis loop methods to formulate the relations between applied force, displacement, damping, and stiffness. Furthermore, an optimization approach was proposed to find the SLS model parameters by searching functions over the frequency domain. The obtained results agree with …

Determination of damping coefficient of soft tissues using piezoelectric transducer

Measuring viscoelastic properties of soft tissues becomes a new biomarker in the medical diagnosis field. It can help in early diagnosis and related fields, such as minimally-invasive-surgery (MIS) applications and cell mechanics. The current work presents a tactile sensor for measuring the damping coefficient of the soft tissues. The proposed sensor can be miniaturized easily and used in MIS applications. Besides the proposed sensor, a mathematical model, based on Jacobsen’s approach, is built to calculate the damping coefficient of the specimens and the surrounding. These damping sources significantly influence the proposed sensor, such as air damping and hysteretic damping. The sensor system principally depends on a piezoelectric transducer, which is cheap, commonly available, and easily integrated into MEMS. To conceptually prove the sensor feasibility, silicon rubber samples with different …

Determination of Viscoelastic Properties For Soft Tissues Using Piezoelectric Bender

The mechanical properties for soft tissues become a new biomarker in the diseases diagnosing field and biomedical Robots. Measuring such properties can help surgeons in diagnosing during minimally invasive surgery (MIS). Furthermore, building a transducer capable of measuring viscoelastic properties could be used in industrial Robot's end effector for handling and grasping tasks. Here, we build a model for a new tactile sensor to measure the mechanical properties for the soft tissue. The proposed model for the sensor is simply consisting of a piezoelectric (PZT) benders, brass layer and prop. These PZT materials are easy to control, have a good frequency response, can be easily miniaturized and integrated into a MEMS system. Moreover, Jacobsen's approach is used to calculate the equivalent damping coefficient based on dissipated work. Three PDMS samples imitating human tissue are used to evaluate …

Characterization of mechanical signature of eutopic endometrial stromal cells of endometriosis patients

Endometriosis affects 5–10% of women in reproductive age and causes pelvic pain and subfertility. Exact etiology of the disease is unknown. Here, we present a microfluidic platform for characterizing mechanical properties of eutopic endometrial stromal cells of endometriosis patients based on cellular deformability inside narrow microchannels. Primary human endometrial stromal cells were isolated from eutopic endometrium of endometriosis patients (4407 cells, from 7 endometriosis patients) and from disease-free women (4541 cells, from 6 control women) and were pumped through microchannels (formed of polydimethylsiloxane (PDMS) by standard soft lithography, with dimensions of 8 × 20 × 150 μm, as width × height × length) at a constant flow rate of 2 μL/min. High-speed imaging was used to capture videos of cells as they flow inside microchannels, and a computer vision code was used to track cells …
