Researchers have developed a machine learning framework for the inverse design of V-beam thermal sensors, aiming to optimize sensor geometry for specific displacement targets while minimizing volume and stress. The approach involves a two-phase solution: first, a neural network is trained as a forward model to map geometric parameters and material constants to sensor responses using a 3000-sample dataset. Subsequently, a gradient-descent optimization is applied to the frozen forward model to simultaneously minimize stress and volume, addressing the ill-posed nature of the problem where multiple geometric configurations can yield the same displacement. This pipeline achieved a Mean Absolute Percentage Error (MAPE) of 4.76% for displacement prediction, with over 70% of predictions exhibiting a MAPE below 5%. AI
