Wearable sensor tracks tumor growth

Futurity: A small, autonomous device with a stretchable and flexible sensor that adheres to the skin can measure the changing size of tumors below the surface, a new study with mice shows. The non-invasive, battery-operated device is sensitive to one-hundredth of a millimeter (10 micrometers) and can beam results…

E-Skin Sensors Go Chipless and Batteryless

IEEE Spectrum: Wearable sensors now often help keep track of vital signs, but these devices usually rely on bulky microchips and batteries. Now scientists have invented a new microscopically thin “electronic skin” that can wirelessly transmit data about the body’s heart…

Tiny caps can measure activity in lab-grown minibrains

Technology Review: Minuscule lab-grown models of human brains can be fitted with caps that measure their activity, just as electroencephalogram (EEG) caps record electrical signals produced by full-size human brains. The minibrains are examples of organoids—three-dimensional clusters of living cells, grown…

New approach can better monitor the placenta

Futurity: Researchers report a new way to monitor the placenta in pregnant patients. By combining optical measurements with ultrasound, the findings show how oxygen levels can be monitored non-invasively and provides a new way to generate a better understanding of…
