Accurate skin temperature prediction is essential in Human Thermal simulation. Humans often wear smart devices during varying levels of activity, so when designing a wearable electronic device, there are multiple design challenges to consider: skin sensation (comfort), the safety of the device, and burn temperatures (ouch!). Because burn modeling is impractical to do the testing on humans, we can use established models. Our thermal simulation software TAITherm offers advanced human thermal comfort and sensation simulation tools that accurately predict skin injury during thermal runaway, including device, skin and contact temperature over time. Thermal discomfort surprises can be avoided through the integration of user comfort testing and physiology-based modeling into the standard design process for wearable electronics.
The comfort and safety of end-users are of utmost importance for product development. Since a customer's experience drives their perceptions of your product, and ultimately market acceptance—your thermal management strategy is critical. The materials you use are essential variables in a successful thermal management strategy. To ensure your chosen materials make the grade, you should use a robust thermal simulation strategy.
Optimize Your Design with Thermal Simulations
Simulations allows you to model the performance of any material or textile under any condition. You can also analyze many variants of your material without having to create multiple prototypes. Your optimization can be done virtually and verified in testing. This process enables faster production while saving you time and resources.
Using TAIThermTM, you are offered a robust thermal and transient simulation method that can produce fast, transient simulations, include human thermal comfort analysis, and account for moisture transport and its effects on your thermal analysis.
TAITherm enables you to model your product under transient conditions, giving you a real-world analysis of your design. Transient simulation offers a detailed analysis that allows you to design optimally, without over- or under engineering.
Transient simulation using TAITherm is fast—delivering simulation results in hours. Be assured; our fast run times do not indicate a lack of accuracy. Our simulations provide accurate thermal data that enable you to make informed design decisions.
Human Thermal Comfort
Know how comfortable your customers will be while using your product. Our Human Thermal Extension provides a comprehensive analysis of human thermal comfort and physiological responses based on your design. Whether designing wearables, activewear, or optimizing cabin comfort, you can know just how customers will feel over time and under varying conditions.
Moisture can significantly affect the thermal behaviors of your chosen materials. When moisture is present in materials, it can change the thermal and evaporative resistances. Changes to the properties can mean your product will operate differently than expected.
For example, if you're designing a winter coat and it becomes saturated with moisture from snow, a person may begin to feel cold as the moisture evaporates more quickly (due to lower evaporative resistance) and draws more energy (heat) away from the body. They will also feel cold because more heat can escape through the clothing layer due to a lower thermal resistance (R-value).
Moisture can also affect applications for other materials such as glass. Automotive designers may be interested in defog/de-ice capabilities that are now able as part of the transient analysis simulation with the Moisture Transport feature.
Utilizing Thermal Manikins
After you've optimized your design with simulation, you can then evaluate the performance of your product using a thermal manikin. A thermal manikin provides the next level of optimization for your garment, cabin, wearable, etc. Once your design is analyzed using a manikin, you can move on to human testing.
By optimizing your design before human subject testing, you can save time and resources by limiting the number of physical prototypes needed and scenarios that need to be tested.

Manage Complex Thermal Challenges
Our team utilizes advanced simulation tools to provide you with fast and accurate data and simulations for transient or steady-state cases for real-world scenarios. We use TAITherm with the Exhaust Extension to quickly create an underbody/exhaust or underhood model that considers the unique physics that the components undergo in cases including hill climbs, trailer towing, hot soaks, or driving cycles. Our method utilizes all modes of heat transfer, so you never miss a thermal interaction.
No matter where your product will operate, it is imperative to understand how the surrounding environment will affect it.
Our expert engineers will create a transient thermal analysis of your design environment to ensure you are modeling the true environment of your product. TAITherm can model environmental and material properties to ensure optimization.
Our Human Thermal Extension is the state-of-the-art technology for predicting human thermal comfort, safety, and effectiveness. It operates within our thermal analysis software, TAITherm, to comprehensively simulate human thermal sensation and thermoregulation under transient and asymmetric environmental conditions. Users can simulate all thermoregulatory responses based on many factors, including activity level. We have developed a comprehensive library of standard human models in various poses, including female and male physiologies. We have also developed an extensive clothing database for rapid model setup.
