Capacitive touchscreens, activated by a finger's conductive touch, are lauded for their durability, high-quality display, and ease of use. Unlike resistive touchscreens, they require no pressure, offering intuitive, gentle-touch interaction. Supporting multi-touch gestures like pinch-zoom, they enhance user engagement. These screens are customizable, conserving space by merging data entry and display, ideal for various modern applications. While pricier and less touch-medium versatile than resistive screens, capacitive ones offer superior clarity, multi-touch support, and an easy-to-clean surface, making them a preferred choice for many contemporary touchscreen devices.

Dive into the world of Liquid Crystal Display (LCD) technology, uncovering its foundation, structure, and operational mechanics. From its inception in 1888 to being a screen powerhouse in a myriad of gadgets today, LCDs have come a long way. Unravel the layers that constitute an LCD, understand how it manipulates light to display images, and how color is rendered on these screens. Despite emerging display technologies, the cost-effectiveness, sharp image quality, and energy efficiency keep LCDs a preferred choice in myriad applications, marking its significant imprint in the digital display realm.

CEiiA, the Centre of Engineering and Product Development that pushes innovation in various sectors, found itself in uncharted territory during the COVID-19 pandemic. Despite no prior experience in ventilator development, the confronting reality of a ventilator shortage prompted the Portuguese company to respond. Racing against time, CEiiA aimed to produce a new, low-cost, easy-to-assemble ventilator that could be locally produced in Portugal, to meet the immediate and overwhelming demand. The result was the Atena – an Invasive Medical Ventilator, a device designed to increase COVID-19 patients' survivability by providing mechanical invasive ventilation.
