Environment and body sensors

The Intuitive Internet of Things runs on data: data about ourselves, about our local environment and from across the internet. That data needs to be reliable and readily available. Which means we need sensor nodes that are highly accurate, small enough to be placed where they are needed and capable of continuous autonomous operation for years.

 

Holst Centre and its partners are pushing back the boundaries of sensor technologies, developing compact sensors for liquid and gas monitoring. For liquid monitoring, we are enabling highly accurate and selective measurement of a wide range of ions with small, very low-power devices. For example, we have created tiny sensors for monitoring pH, conductivity, calcium, chloride and others. This opens up new applications in environmental and body monitoring: from wearable health sensors through smart packaging for food to portable air and water quality detectors.

 

We are exploring both solid-state sensors for long-term monitoring and flexible devices for wearable and disposable sensing patches. In both cases, we employ production techniques that are easily scalable to high-volume manufacturing. Our focus is on developing new sensor building blocks such as ion-specific membranes, miniaturized multi-ion and reference electrodes, and conductivity sensors. And then integrating them into complete node demonstrators and prototypes for specific applications.
