The Implantable Microsystems for Personalised Anti-Cancer Therapy (IMPACT) project aims to produce an implantable wireless sensor device for monitoring tumour physiology. Real-time measurements will be used to improve radiotherapy by allowing treatment to be responsively delivered at the most effective time and location. We are developing miniaturised microfabricated sensors for measuring local oxygen concentration and pH within the tumour, using technologies that are amenable to integration on CMOS. In addition, we have established proof of concept for a range of electrochemical biosensors that can respond to enzyme biomarkers. Together these sensors will allow comprehensive monitoring of tissue physiology before and after radiotherapy treatment. For clinical use, the complete system will be equipped with circuits for wireless power and communications and packaged in biocompatible materials. This is a very challenging application for sensors integrated on CMOS. Here we provide a brief background to medical aspects of the work and describe our progress towards solving the engineering challenges it has presented.
