No they are not multiple slices of Image Sensor, but they have stacked the image sensing part over the circuit part, meaning they have differentiated the electronic circuit part and the image sensing part on the semiconductor subtract. This way they are being able to have better control over the image sensing.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
