Thousands of Swedes are inserting microchips into themselves – here’s why

Thousands of Swedes are inserting microchips into themselves – here’s why Chips with everything. www.shutterstock.com Moa Petersén, Lund University Thousands of people in Sweden have inserted microchips, which can function as contactless credit cards, key cards and even rail cards, into their bodies. Once the chip is underneath your skin, there is no longer any need to worry about misplacing a card or carrying a heavy wallet. But for many…

Wearable health monitoring with stretchable nanogenerators

So far, most of the developed self-powered piezoelectric devices are rigid or have limited lateral stretchability and could not be used to harvest energy from lateral strain, which greatly limits their applications on large strain deformation. In new work, researchers have successfully fabricated a piezoelectric nanocomposite device with good transparency, high stretchability, and self-powered sensing characteristics. Attached to the human body, it can harvest biomechanical energy and monitor physiological signals.…
