Multimodal Temperature Sensing Using Electromechanical Impedance (EMI) for Structural Health Monitoring

IEEE Sensors Journal
In this article, we propose a new multimodal sensing approach in which electromechanical impedance (EMI) signatures are used to sense temperature in addition to structural health monitoring (SHM) for which the technique is commonly used. Here, we use machine learning to estimate temperature differences between signatures, enabling the EMI sensor to ...

A Two‐Stage Characterization Pipeline and Open‐Source Framework for Reproducible Tactile Sensing

Advanced Intelligent Systems, EarlyView.
The same soft tactile sensor returns different numbers when embodied in different robots. This is an Embodiment Gap that no shared framework currently captures transparently. A two‐stage characterization pipeline, paired with a FAIR open‐source digital datasheet, decouples intrinsic sensor behavior from embodiment effects and condenses cross‐laboratory
