E-Mitter Battery-Free Implantable Transponders

Using telemetry to provide temperature, gross motor activity and heart rate data. An E-Mitter is a small implantable transponder that is powered by capturing energy from electrical fields generated by the ER-4000 Energizer/Receiver. This allows the E-Mitter to operate without batteries and remain implanted indefinitely to monitor the subject's temperature, activity or heart rate. As a result, high costs and downtime of explantation, refurbishment and reimplantation are avoided.
