Optogenetics uses light stimulation to control the excitation, inhibition, or signaling pathways of optically excitable cells and provides a powerful tool to diagnose and treat, as well as understand, numerous neurological and psychiatric diseases and disorders. Modified neurons can be activated or silenced by different light frequencies. However, the...

Magnetic field sensing has countless applications ranging from aircraft testing to detection and security applications. However, there are two major dilemmas with current sensors. First, magnetic field sensors have a low sensitivity and are unable to accurately detect failures and defects in low electrical fields. Furthermore, current sensors are only...
