Plastic Logic, a leader in the design and manufacture of flexible, glass-free electrophoretic displays (EPDs), has announced a new flexible 5.4in colour display that is set to revolutionise smart wearable devices.
Close scrutiny of basic vital functions supports a patient's care and recovery, but hospital resources and existing technological solutions might not be adequate to the task. VTT Technical Research Centre of Finland and its partners are developing wearable sensors such as smart patches that are almost unnoticeable for the user, which keep track of the patient's basic vital functions without interruption, sending the information wirelessly to a monitoring system.
Nanoengineers at the University of California San Diego have developed a “wearable microgrid” that harvests and stores energy from the human body to power small electronics. It consists of three main parts: sweat-powered biofuel cells, motion-powered devices called triboelectric generators, and energy-storing supercapacitors. All parts are flexible, washable and can be screen printed onto clothing.
