title: Implantable telemetry system for long-term EMG.
abstract: Our aim was to record the uterine muscular activity of the badger or the fox. For long-term physiological experiments, commercial transmitters cannot be used. The operating time of commercial transmitters with a single set of batteries does not exceed 15 days at the most. In addition, the dimensions render implantation of such equipment impossible. It is not always necessary to record permanently but sometimes a few minutes a day are sufficient to assess the evolution of a phenomenon. We have conceived and constructed a miniature implantable receiver module which allows the transmitter to be switched on and off in order to be operated only during selected periods of time.
