Does anyone have a good idea for use cases for these? It seems a lot of use cases for "small, cheap electronics" are already covered by RFID, where you keep the processing "smarts" in the device that reads the RFID. So when do you need actual computation to take part on each tiny chip? Some kind of "smart dust" mesh network? (assuming you can pair these chips with an antenna and power source)
- __alexs 4y agoThese devices are something like one tenth the price of a regular passive RFID tag.
- Zenst 4y agoThat may well be down to the cost of the metal to make the inductive coil. Now if you add the ability to do comparable RFID comms using this chip, then how would the costs compare is what we do not know.
- __alexs 4y agoCopper is definitely not cheap but I doubt there's more than 0.5g in most passive RFID tags.
- chillingeffect 4y agoSure... replace any barcode with one and it can remember its history of scanning.
- incrudible 4y agoWhat is the use of that, then? Also, how does that require computation?
- smaudet 4y agoJust brainstorming, if the chip is large enough you could just plop a reader down on it.... not as convenient as RFID but then you could sell a reader which reads info off of bananas, e.g. Why the consumer would want to read info off of a banana, great question, but.
- squarefoot 4y agoYou had me chuckle:) There are however serious uses for very cheap sensors with brains, for example in food boxes to check that none of the packages was exposed to critical temperature unintentionally, or even prevent frauds in those places where they relabel expired food as fresh: a small chip that senses everything including air pressure besides carrying the manufacturing date and duration information,could also signal that the contents are non edible as soon as it detects that the vacuum bag has been tampered with.
