ULP-AID

Ultra Low Power Animal Implant Devices (ULP-AID) are implants that are designed to transmit digital information for the purpose of providing a one-way radio link between the ULP-AID and an external receiver. These implants are used for medical diagnostic purposes such as measuring body temperature, blood pressure, heart rate, and hydration level, either as a single physiologic parameter measurement or in multiple configurations.

Most ULP-AID devices make use of inductive loop techniques. This magnetic field technology allows lossless penetration of most materials encountered in medical environments including animal tissue. The devices only radiate electromagnetic energy when activated by a laboratory technician.

The animal implants consist of two sections, the physiologic parameter sensor or sensors and the transmitter section to enable the telemetry function. The RF pulse drive circuit is typically integrated into a hybrid chip that drives an internal coil capacitor circuit. This coil is the radiating antenna for the implant. Generally, the package is sealed in a suitable polymer case with sensor leads extending through the case.
