Yes, if the problem is viewed broadly, eg. passive packages like RFID tags. Power consumption has been a focus area in chips since forever. For active chips, it's not possible if the problem is viewed narrowly however it's possible to have a package that contains both power generation capability (eg. solar, kinetic) and highly power efficient, sporadic processing which probably exist already. Major application areas would be long-lived deployments (eg. animal tags, probes, implants, wearables).
