A vision of Z-devices - page 2 Many products are assemblies of lots of smaller parts. I envision a transformation in the way we manufacture such products. For example, when I look at a toaster, I see dozens of Z-devices within it. There is a power switch. This little button contains a Z-chip. Self-powered and radio-linked. This switch can be manufactured independently, by a supplier to the toaster assembly company. The switch could be removed, put into a pocket, and taken to a far-off city. Pushed there, the toaster back home would start toasting! I also see a few heating coils. These too are Z-devices, independently manufactured, each with their own Z-chips. There are a few temperature sensors throughout the toaster, each a Z-device, self-powered and radio-connected. No wires. There are several spring-operated objects to pop up the toast, or perhaps a few motors for the same purpose. Each of these have self-powered radio-linked Z-chips, and are independently manufactured Z-devices.
