The development of an active implantable device for measuring electrocardiogram (ECG) is presented. The study is a part of a project which aims at developing implantable ECG instrumentation with wireless data and power transfer ( ). The developed implant presented here has all the measurement electronics as well as power and data(More)
An implantable wireless, inductively powered ECG-monitoring device has been tested both in vitro and in vivo. Measurements were done in saline, on the body surface and in cows. Measurement results are reported and some considerations about the device suitability for a long-time monitoring are made.
This paper describes wireless measurement platform, which uses inductive power and data transmission and provides up to four analog measurement channels. Platform is powered by inductive coupling using the 125 kHz magnetic field. Data transmission is realized by modulating the magnetic field. The platform has up to four 10-bit analog channels. The sample(More)
