Abstract
A radio device for implantation in an animal. The radio device comprises a capsule encapsulating at least one of a radio receiver and a radio transmitter. Also disclosed herein is a method for making a radio device for implantation in an animal, a method for providing electrical power to a radio device attached to an animal, and a method for implanting a radio device into an animal.
Claims10
A radio device for implantation in an animal, the radio device comprising:
- a radio-frequency identification (RFID) device that is responsive to an interrogating radio wave in the ultra-high frequency (UHF) band received by a dipole antenna,
- wherein the RFID device and the dipole antenna are electrically connected and attached to an antenna substrate, and
- wherein the RFID device, the dipole antenna and the antenna substrate are encapsulated by a coating to form an encapsulated device having a maximum width of less than 1 mm and a maximum height of less than 0.5 mm that is configured to be implanted in a tail of a rodent beyond a hairline of a torso of the rodent using a needle having a diameter of 20-22 AWG.
An improved radio device suitable in size and material for implantation in a rodent using a cannula, the radio device comprising a radio-frequency identification RFID device, an antenna in signal communication with the RFID device, and an antenna substrate, wherein the improvement comprises:
- the RFID device is configured to be responsive to an interrogating radio wave in the ultra-high frequency UHF band and the antenna is a dipole antenna that receives the UHF band interrogating radio wave;
- and
- the radio device is encapsulated by a biologically inert coating to form an encapsulated assembly that has a maximum transverse dimension of less than 500 μm and is configured to be implanted under the skin in a tail of the rodent beyond a hairline of a torso of the rodent using a cannula having an inner diameter of a lumen in the range from 0.6 mm to 0.41 mm.
