The working principle of digital calipers is mysterious enough that we’d never think to dismantle, much less improve them, right? Well, think again, as [Limi DIY] retrofits the processing ...

Layers of silicone are sandwiched between two lengths of silver-plated conductive fabric forming — by some approximation — a capacitance sensor. While the total surface area doesn’t change ...

Numerous options can serve the purpose, including sensors based on variable capacitance and piezoelectric sensors, further assisted by thermographic and other technologies. Predictive Maintenance ...
