Microresistor Beam
Application ID: 23541
Microresistors allow for quick and accurate actuation or structural movement directly related to the electricity that is applied to them. Microresistors can be used in many applications where small perturbations or deflections are required to be applied to devices, almost instantaneously.
The Microresistor Beam application illustrates the importance of fully coupled, multiphysics simulations. An electric potential is applied across a small resistor and the deformation, temperature, and electric potential within the beam are computed.
This application allows for the geometric dimensions to be varied, along with the material properties, electrical conductivity, and applied voltage. Based on the results, you can design the right microresistor for your device.
This application example illustrates applications of this type that would nominally be built using the following products:
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the Specification Chart and make use of a free evaluation license. The COMSOL Sales and Support teams are available for answering any questions you may have regarding this.
