Performance Optimization by Adaptive Control of Material Properties in Portable Electronic Devices

We evaluate the potential benefits of using tunable material properties within portable electronic devices for increasing total power generated across different operating scenarios. In these devices, in addition to die temperature limits, user-exposed device skin must be kept ergonomic comfort requiring adaptive control balance constraints. Present thermal management strategies rely on allowed amount heat generation (performance throttling) maintain and temperatures permissible limits as conditions fluctuate. To address this drawback, we investigate performance offered by integration layers into a representative that could adaptively their properties, so maximize dissipation while preserving junction prescribed bounds. A steady-state model is employed identify required conductivity performance. The predicts materials offer $\sim 15$ %–20% increase maximum can dissipated, due modulation junction-to-skin resistance, platform range conditions. demonstrate case study understand effect introduction at peak dissipation, considering same upper lower bounds form factors. summary, work critically identifies need target achieve optimal with realistic modest tuning ratios effective conductivity, which used future development controls application.
