I wonder if there is anything to come from wireless power delivery inside chips. If the entire chip was bathed in constant RF, then bits of the chip could pick up power when and where needed via tiny antennas harvesting the RF field. It would require some very tricky control of wavelengths but might eliminate many wires. Lasers might also offer interesting possibilities for delivering power without wires. How small can we make a photovoltaic panel?
- hinkley 5y agoIf that were possible, wouldn’t capacitive coupling be simpler and achieve a similar goal?
- KirillPanov 5y agoIf you try sending RF power to LSI-scale antennas, the LSI-scale signal wires near them will be antennas too.
- ruslan 5y agoSince antenna efficiency directly depends on it's size-to-wavelength (resonance), to get them working we have to deliver power at extremely high frequencies, like 3e16 Hz I quess, which is not feasible.
