Description

<p>When trying to sense and transmit intra-corporeal biological signal(s), unpowered passive telemetry is known solution for simplicity, size and weight and complexity reduction, and longer lifetime of sensor device, in spite of variety of design restriction. In our prior researches for encapsulated intra-corporeal pressure and/or soundscape telemetry sensor we used both powered (active) and unpowered (passive) methods, such as primary cell, secondary cell, body-fluid fuel cell, electromagnetic feeding, optical feeding, etc., however, all having its intrinsic pros and cons to prevent more extensive development for actual clinical use devising. In this study we use passive (non-power fed) sensor device on site with either ultrasonic or optical excitation and electromagnetic response reception. The method and system have unique affordable characteristics such that, unlike bidirectional electromagnetic coupling, system do not need T-R (transmission and reception) separation within a same kind of signal energy.</p>
