Design outcomes
Primary
| Measure | Time frame |
|---|---|
| To evaluate whether IEM magnetic field signals generated inside the body can be detected externally using a TMR sensor at a distance of 1 cm from the body surface. | — |
Secondary
| Measure | Time frame |
|---|---|
| 1) Total number of packets (data packets, beacons) 2) Number of data packets and beacons, respectively 3) Position of the TMR sensor at which the IEM magnetic field signal reaches its maximum amplitude 4) Dependence of the IEM magnetic field signal amplitude on the distance between the body surface and the TMR sensor 5) Estimated distance dependence of the IEM magnetic field signal amplitude from the IEM chip | — |
