“…A more effective shape preserving method has been embedded into the Mass Spring Systems (MSS) where the springs are placed at the mesh nodes. They are also known as the Local Shape Memory [5]. These springs have been employed to simulate non-linear skin behaviour of a virtual thigh [6] [7].…”

This paper introduces volume springs that provide the volume effect to a surface model when it is deformed. The estimation of the properties of the model takes the real material properties into consideration, where each spring stiffness is derived based on the elasticity, rigidity and compressibility modulus. The proposed model can be adopted to simulate soft objects such as a deformable human breast, and it can be further extended to address other material properties.

This paper introduces a surface alternative to the volume model commonly employed in soft object simulation. This is inspired by a significant interest in employing the surface data due to its simplicity. However, there are issues in properties estimation and volume preservation. Therefore, the aim of the ongoing research includes exploring the potential of a surface mass spring model with shape-preserving springs for volume simulation. The approach illustrates the possibility of deriving the spring stiffness at runtime based on the real material properties as well as achieving a global shape deformation despite the non-existence of internal volume. The proposed scheme can be further explored to address other material properties.

“…Because our sensor consists of two springs and each spring contact the tissue at a different point, the tissue between the two contact points is affecting the force generated at each spring. According to the soft tissue discrete model (15) , a tissue can be represented as a network of mass (node) spring system. In order to simplify the analysis, this discrete model (network) is reduced to two vertical springs and one horizontal spring, which represent the cross talk effect as shown in Fig.…”

Design and Simulation of a Tactile Sensor for Soft-Tissue Compliance Detection

Non-memberA detailed design procedure for a tactile sensor for compliance detection is developed. The sensor principle is based on the concept of applying two springs, with considerably different stiffnesses, to soft tissue for compliance detection. The spring stiffnesses are chosen to be associated with the soft tissue properties. The sensor design parameters are optimized to give high sensitivity and linearity of the sensor output with taking into account the effect of crosstalk between two springs due to the tissue deformation. A finite element model is developed to investigate the sensor performance with the designed parameters using two types of spring end, namely cubic and spherical in shape. The results show a significant stability of reading with the cubic end rather than the spherical one during pushing the sensor against a tissue. Finally, the same finite element model is used with changing the distance between the spring ends to show the crosstalk effect due to the tissue deformation.
