Autonomous Microsensor Control Systems
Medical Device Link has an interesting story on wireless microsensors written by Campus Micro Technologies, a German sensor system integrator. The application for microsensors discussed includes the creation of partly and fully autonomous therapeutic feedback (closed-loop) control systems. The idea is that this “new” type of implantable pressure monitoring system can provide long-term monitoring inside the human body (at least 10 years or more).
Requirements for such a system include minimal power that is supplied from outside the body rather than incorporating a battery, which limits the lifetime of the implant. Packaging and assembly of the implant is also critical regarding biocompatibility and the long-term functioning of the system. The story provides examples of work being done on developing these systems for measuring intracranial pressures, continuous measurement of intraocular pressure, and for use as feedback to ensure the quality of therapy delivery.
