Miljøenergihøsting

Miljøenergihøsting, also known as energy harvesting or power harvesting, refers to the process of capturing and converting small amounts of ambient energy into usable electrical power. This ambient energy can originate from various sources present in the environment, such as solar radiation, thermal gradients, kinetic motion, radio frequency waves, or even vibrations. The goal is to provide a continuous or intermittent power supply for low-power electronic devices, thereby reducing or eliminating the need for batteries or conventional power sources.

The core principle behind miljøenergihøsting involves a transducer that converts the ambient energy into electrical energy. For example, photovoltaic cells convert sunlight into electricity, thermoelectric generators utilize temperature differences, and piezoelectric devices convert mechanical stress or vibration into electrical signals. The harvested energy is typically stored in a capacitor or a rechargeable battery, which then powers the electronic device.

Applications for miljøenergihøsting are diverse and expanding. They include powering wireless sensors in the Internet of Things (IoT), wearable electronics, remote monitoring systems, medical implants, and even small consumer devices. By enabling self-powered or long-life operation, miljøenergihøsting contributes to increased sustainability, reduced maintenance, and the deployment of devices in locations where traditional power sources are inaccessible or impractical. The efficiency and power output of energy harvesting systems are constantly being improved through advancements in transducer materials and power management circuits.
