Stretching a strain gauge causes a change in its resistance ... Instead we directly use the differential voltage between the two sides of the bridge, V O. V O is then proportional to the change ...

Here’s a neat trick for your next 3D-printer build or retrofit: a Z-axis sensor using a DIY strain gauge made from SMD resistors. We’re betting it could have plenty of other applications ...

A new smart garment with deep learning sensors offers precise, nonintrusive monitoring of sleep disorders, improving accuracy and user comfort in sleep health.
