Medical technology is just one example of a field in which flexible and elastic electronics can be successfully employed. Applications range from monitoring body temperature and respiratory rate to use in electrocardiography (ECG), electroencephalography (EEG) or measuring oxygen saturation in arterial blood. Such materials when used in smart medical patches are suitable for measuring, monitoring and transmitting heart rate data to wirelessly connected devices.

The advantage of printed sensors is that they are less bulky and also relatively easy to integrate, thus offering superior wearing comfort. The low manufacturing costs of printed electronics is also a key factor, as is the trend towards medical sensors being used only once or for a single patient. Printing processes reduce costs significantly. However, there is still a need for further development in the automated mass production of printed electronic components. Disposable sensors are more hygienic and can perform therapeutic functions. Printed electronic patches worn on the body contain sensors, displays, solar cells and rechargeable batteries.
