Ultra-Low Power: Microcontroller Standby Current to 130uA with OPEnS Power Control Board

At the OPEnS Lab, a key focus for our projects is achieving exceptionally long battery life. This was particularly true for the OPEnSampler, a device that presented a unique challenge due to its need for simultaneous operation at three different voltage levels (3.3V, 5V, and 12V). While existing circuits using MOSFETs could manipulate power sources […]

Breathe-Easy EEG

Introduction By measuring brain activity using electrodes and an amplifier circuit, electroencephalograms (EEGs) are at the intersection of electrical engineering and neuroscience. By using signal processing techniques, we can examine the effects of external stimulation, such as music and meditation, on brain waves. We primarily examined alpha and beta brain waves in our EEG. While
