Sensor technologies and energy harvesting for wearable and implantable electronics
The proliferation of wearable devices for monitoring wellness and healthcare is part of the broader shift from centralised, cloud-based, Internet of Things to more decentralised autonomous Edge computing devices, as a key enabler for the “Fourth Industrial Revolution” [1].
Of course, this transition means not only more ubiquitous smart systems but also more energy and computationally efficient hardware. personalised to the actual user needs
This also means more Edge devices gradually becoming portable and autonomous from the energy and data processing standpoints, so that they can be embedded into everyday objects, for either long-term operations at low duty cycle, as in the case of sensor networks, or with shorter lifetime, as for instance in the case of disposable electronics, smart labels, single-use sensors for personal diagnostics and others.
Printable sensors and electronic technologies are unique enablers of flexible, conformable, lightweight, skin-compliant, and bio-compatible integrated smart systems, for multiple applications in personalised diagnostics and therapeutic sectors. Solely powering autonomous IoT devices with batteries may not sustain the growing complexity and size of the IoT ecosystem as it proceeds to one trillion nodes. For that leveraging energy storage with ambient energy harvesting technologies might help mitigate the sustainability challenge.
Also, when it comes to sensors and electronics for data acquisition and processing, the design and development of ultra-low power printed electronic circuits and sensors, made of bio-compatible and eco-friendly materials and manufacturing processes, plays a critical role in managing the power budget at the system level, and reducing the burden of batteries and conventional electronics to the environment.
In this talk I will discuss design, advanced materials and heterogenous integration technology requirements for next generation wearable and implantable electronics, with attention to their sustainability and end-of-life.
Examples of our recent works in thin-film, organic and graphene-based wearable biosensors [2]-[4], energy harvesters and storage technologies [5]-[8], and ultra-low power printed electronics [9]-[10], flexible, stretchable and biocompatible substrates [11]-[13] will be presented that are suitable for integration in next generation wearable products.
