Lecture

Flexible Probes: Mechanics and Design

Description

This lecture covers the concept of critical strain in materials, discussing its importance in preventing mechanical fracture and its application in designing flexible probes. It also explores the mechanics of bending a film-on-substrate stack, comparing stiff and compliant substrates and explaining the location of the neutral plane. Additionally, it delves into the calculation of strain at the top surface of a structure, providing formulas based on thickness, bending radius, and material properties.
