I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller and a piece ...

Functional near infrared spectroscopy (fNIRS) is a non-invasive and wearable optical imaging modality that has been used for many applications to monitor hemodynamic response in the clinical setting ...

The primary goal of this thesis was to create a low-cost Arduino-based fNIRS system and its use in a variety of clinical settings. While this system was used for several clinical applications, in this ...
