It might have to do with government restrictions on devices that can be used for targeting people – the Panasonic GridEYE is considered a “controlled device” here in the USA. I was going to do a product based on it (i.e. it can tell you how many people are in a room) but the usage restrictions made it too difficult to sell.
So, I just open-sourced the project

and people can build their own if they want to try it out.
 3D-IC Design Challenges and RequirementsSponsored by Cadence Design Systems While there is great interest in 3D-IC technology, it is still in its early phases. Standard definitions are lacking, the supply chain ecosystem is in flux, and design, analysis, verification, and test challenges need to be resolved. Read this paper to learn about design challenges, ecosystem requirements, and needed solutions. While various types of multi-die packages have been available for many years, this paper focuses on 3D integration and packaging of multiple stacked dies. |
