Bridging the micro and macro: enhancing MEMS education through cross-disciplinary analogies

Micro-Electro-Mechanical Systems (MEMS) are integral to modern life, with applications spanning smartphones, airbag sensors, and beyond. However, the education of students on MEMS in an engaging and interactive manner poses a significant challenge due to the nano-scale and hermetically sealed architecture of these devices, which precludes direct observation and interaction. To address this, we exploit the cross-disciplinary attributes of MEMS by drawing analogies between MEMS devices and life-sized structures familiar within mechanical or civil engineering. For example, a MEMS cantilever is compared to a balcony, a bridge, or a diving board, and demonstrated in class using simple, cost-effective props such as rulers of different lengths and stiffness. Poisson's ratio, is illustrated using rubber exercise bands or even edible jelly sweets! This cross-disciplinary approach has been implemented in class, providing a student-centred learning environment through hands-on demonstrations and interactive discussions. Feedback collected from students reflects an enhanced appreciation of the connection between life-sized mechanical structures and nano-scale MEMS devices.
