Wireless implantable biomicrosystem for bladder pressure monitoring and nerve stimulation

In recent years, the wireless implantable biomicrosystems provide desirable approach for long-term nerve stimulation and physiological signal monitoring. This study aimed to implement implantable biomicrosystems which include a bladder pressure sensing module and a microstimulator. For long-term implantation, a transcutaneous magnetic coupling technique was adopted for transmitting power and commands into the microstimulator. The adjustable stimulation parameters, including the stimulation intensity and frequency, can be controlled via the external module. For telemetric pressure sensing system, the wireless module is designed for bladder cavity pressure measurement.
