TLDW : ( Custom old tech (180nm) integrated chip gets energy from RF harvesting ~5uW -> x100 differential amplifier -> 16 channel - 16 bits ADC (0.5Hz-256Hz) -> ultra low power custom RF transmitter) * 64 pcbs = 1024 channels -> Base station to collect and process the data.

Very cool tech. No battery needed (aka inherently safe). Need to shave your head. Read-only (as opposed to something like neuralink which is read-write).
