One of the great things about Moore’s law that is sometimes overlooked is that even though computing capabilities have expanded at a tremendous rate, the power consumption for those same transistors that are being packed together have gone down at an even faster rate.
This announcement from the University of Illinois at Urbana-Champaign of the demonstration of a high-performance 3D micro-battery suitable for large-scale, on-chip integration may have long-lasting impact to the Internet of Things.
“Due to the complexity of 3D electrodes, it is generally difficult to realize such batteries, let alone the possibility of on-chip integration and scaling. In this project, we developed an effective method to make high-performance 3D lithium-ion microbatteries using processes that are highly compatible with the fabrication of microelectronics,” – Hailong Ning, a MatSE graduate student
If this technology can be produced reliably, I’d expect it to show up in many ways quickly, since access to a power source is critical to any sensing or distributed computing approach, allowing for greater flexibility in where to place ‘things’. Having the manufacturing process compatible with the chip making process should make for rapid adoption.
