In this paper, the vibration characteristics of stapes, driven by the implanted differential floating mass transducer (DFMT) in the human middle ear, are analyzed by using an electrical model. The electrical model has been simulated by using the PSpice, in which the simulated results are compared with the experimental results by using the fabricated DFMT and the human temporal bones.

In this paper, the pressure monitoring telemetry system has been designed and implemented for an accurate pressure measure-ment inside the gastrointestinal tract with minimizing pain and inconvenience. The system is composed of a miniaturized pres-sure measurement capsule and an external receiver. The per-formance of the telemetry capsule for monitoring pressure in the gastrointestinal tract is demonstrated by the results of animal in-vivo experiments.
