Toward a low-cost, low-power wearable sensor for temperature and respiration

Engineers at the University of California San Diego are developing low-cost, low-power wearable sensors that can measure temperature and respiration–key vital signs used to monitor COVID-19. The devices would transmit data wirelessly to a smartphone, and could be used to monitor patients for viral infections that affect temperature and respiration in real time. The research team plans to develop a device and a manufacturing process in just 12 months.

Breaking the Size and Speed Limit of Modulators: The Workhorses of the Internet

SUMMARYResearchers developed and demonstrated for the first time a silicon-based electro-optical modulator that is smaller, as fast as and more efficient than state-of-the-art technologies. By adding indium tin oxide (ITO) – a transparent conductive oxide found in touchscreen displays and…

Paramagnetic Spins Take Electrons for a Ride, Produce Electricity from Heat

Local thermal perturbations of spins in a solid can convert heat to energy even in a paramagnetic material – where spins weren’t thought to correlate long enough to do so. This effect, “paramagnon drag thermopower,” converts a temperature difference into an electrical voltage.
