MIT researchers created tiny (0.002 square inches) chips that could help combat supply chain counterfeiting.
It’s millimeter-sized and runs on relatively low levels of power supplied by photovoltaic diodes. It also transmits data at far ranges, using a power-free “backscatter” technique that operates at a frequency hundreds of times higher than RFIDs. Algorithm optimization techniques also enable the chip to run a popular cryptography scheme that guarantees secure communications using extremely low energy.
Sounds interesting. I wonder if these could be used for more than counterfeits.
