In Zahlen
Engineering researchers at Penn State University have developed a new integrated circuit (chip) that operates entirely on ambient sunlight and eliminates the need for a battery. This innovative technology combines energy generation, chemical sensing, and computing processes in a single structure, aiming to provide great convenience for devices in remote or inaccessible locations where replacing batteries is difficult.
To eliminate the area and wiring losses associated with battery-powered systems, the developed chip vertically stacks all its components within a single structure. While the silicon photovoltaic module at the base converts ambient light into electrical energy, graphene-based sensors react to liquids, and the middle layer formed by two different semiconductor materials (MoS₂ and WSe₂) processes this data.
Although it is currently a small, purpose-built chip, this research establishes a crucial foundation for future technologies. The adoption of this design philosophy by larger-scale circuits could pave the way for innovative, low-power-consuming solutions, particularly for the Internet of Things (IoT) and edge computing systems.
