Zinc oxide (ZnO) is a common ingredient in sunscreen lotions. Less well-known is the fact that it’s also a wide band gap (WBG) semiconductor (3.4 eV). As a nanomaterial, ZnO is being used to develop a wide variety of sensor technologies. Sensor applications for ZnO include health monitoring, chemical sensing, biomedical, and environmental sensors. Some […]
Devices that generate both video and audio output have the option to either display it on an onboard screen or transmit the signal to an external monitor or display. To achieve the latter, a cable system with integrated connectors is required. This article section outlines the evolution of interconnect technology over several years (Figure 1). […]

Malawi has one of the world’s lowest electricity access rates—just 14.1% of the total population have access to the main grid. In rural areas, the electrification access rate is even lower, estimated at […]
