ENGLISH ABSTRACT: The need for proper fatigue detection and mitigation is made clear in research, with failure to detect fatigue resulting in significant societal health repercus- sions. Currently, there are limited hardware systems dedicated to the monitor- ing of fatigue-related biometrics. The devices that do attempt to provide this information are often impractical due to their size, required expertise and cost constraints. Access to these technologies by a broader population is therefore limited. Wearable health devices could provide a more practical solution. A data capture system was designed and implemented that records PPG and in- ear EEG information. The device was created to be inexpensive and portable. The in-ear EEG results obtained showed the detection of a statistically signif- icant difference in alpha attenuation levels, which are closely associated with the state of alertness or drowsiness. While the acquired heart rate and blood oxygen saturation measurements showed a close correlation with an FDA ap- proved pulse oximeter. Although the number of trials conducted was limited, the results show promising performance. This project is a stepping stone in the pursuit of an affordable fatigue monitoring solution that can mitigate the human-cost incurred on account of fatigue. AFRIKAANSE OPSOMMING: Die behoefte aan behoorlike opsporing en versagting van moegheids vlakke word in navorsing duidelik gemaak, met die versuim om moegheid op te spoor kan lei na ernstige gesondheidsgevolge vir die samelewing. Tans is daar be- perkte hardewarestelsels wat toegewy is aan die monitering van biometriese seine wat verband hou met moegheid. Die toestelle wat probeer om hierdie in- ligting te verskaf, is dikwels onprakties vanweë hul grootte, vereiste kundigheid en kostebeperkings. Toegang tot hierdie tegnologieë deur ’n breër bevolking is dus beperk. Draagbare gesondheidstoestelle kan ’n meer praktiese oplossing bied. ’n Data-vangstelsel is ontwerp en geïmplementeer wat PPG- en binne- oor EEG inligting opneem. Die toestel is geskep om goedkoop en draagbaar te wees. Die binne-oor EEG resultate wat verkry is, het die opsporing van ’n statistiese beduidende verskil in alfa-verswakkingsvlakke aangetoon, wat ’n noue verband hou met die toestand van waaksaamheid of slaperigheid. Terwyl die verwagte hartklop en bloedversuurstofversadigingsmetings ’n noue verband toon met ’n FDA-goedgekeurde polsoksimeter. Alhoewel die aantal proewe wat uitgevoer is, beperk was, toon die resultate belowende prestasies. Hier- die projek is ’n springplank in die strewe na ’n bekostigbare oplossing vir die monitering van moegheid wat die mensekoste wat weens moegheid aangegaan word, kan versag.
