Om avhandlingen

Electrochemical biosensors are important tools in healthcare, environmental monitoring and food safety, providing accurate information about a chemical quantity through ease-of-use and low cost. Examples are detecting breast cancer cells in blood, monitoring carbon monoxide levels in air, and determining the presence of e.coli in food or drinking water. Although the sensors can be realised in a low-cost regime, the supporting instruments driving the sensors can be expensive, technically complex and bulky. This renders most freshly developed assays unsuitable for field-trials and mobile applications.

To this end, we have provided a generic, stamp-sized, wireless and flexible platform, the ecFlex, built from off-the-shelf components, capable of driving electrochemical sensors through a fraction of the cost of a laboratory instrument. Furthermore, the hardware and software designs have been made available to the public, enabling developers to tailor the design to their own needs. In this respect, the system was shown to be able to determine the «hotness» in chili sauce as well as measuring the levels of pH and chloride. The perhaps most successful electrochemical
sensor application is that of diabetes management through measuring blood glucose. 

Bringing that technology to where it is today has taken more than forty years of development and billions of Euros. This technology is bound by intellectual property rights, and is made specifically for the accompanying sensor. The ecFlex, however, is free to use for all, and can support an array of different sensors, owed to the system’s configurability.

This project attempts to leverage the technology behind the blood glucose home monitoring and make it available to any sensor, such that it may be utilized by smart sensors, internet-of-things and wearable electronics, to name a few. This technology will therefore contribute towards lowering the barriers associated with
transferring elegant laboratory assays to real-life applications.
