  • Now MIT researchers have developed a “smart” diaper embedded with a moisture sensor that can alert a caregiver when a diaper is wet.
  • RFID tags don’t require batteries; they receive energy in the form of radio waves emitted by an RFID reader.
  • When an RFID tag picks up this energy, its antenna activates the RFID chip.
