Boosting Battery Life Tenfold: NUS Unveils Energy-Efficient Chip for AI Devices


May 22, 2024

Tech News

The National University of Singapore (NUS) has unveiled a new chip technology in collaboration with industry partners. This technology, demonstrated in fully-depleted silicon-on-insulator (FD-SOI) technology, aims to significantly enhance the energy efficiency of AI-connected devices. It could potentially extend the battery life of wearables and smart objects by tenfold, support heavy computational workloads for IoT applications, and reduce power consumption in wireless communications with the cloud. The innovation will be promoted through the FD-SOI & IoT Industry Consortium to encourage rapid industry adoption.

Microsoft has announced its plans to make Windows an AI operating system and has launched a new lineup of Windows machines called Copilot+ PCs. These devices, designed to be AI-first, will feature dedicated AI chips (NPUs) for powering AI experiences like Recall, which helps users find previously accessed content. The first Copilot+ PCs will include Qualcomm’s Snapdragon X Elite and Plus chips, promising long battery life and high performance. Microsoft has also unveiled new Surface devices focusing on performance and battery life, alongside introducing features like Recall for Windows 11, which aids in finding past activities and content on PCs.

Emerging research suggests that pink noise, known for its soothing sound similar to rain or the ocean, could potentially improve sleep and memory. Scientists at Northwestern University are studying how pink noise can enhance the slow brain waves associated with deep sleep. Early studies show promise in improving memory and relaxation, though more research is needed to confirm these benefits.
