The longer the light is on, the more the polymer get altered. By using a shadow mask, the UV light is applied to just the desired areas, tuning the circuit behavior.

Tuning flexible circuits with light Date: September 21, 2021 Source: Osaka University Summary: Researchers created flexible integrated circuits precisely tuned by illuminating an organic polymer ...

Nanophotonic circuits are integrated optical devices that control and manipulate light at the nanoscale. They consist of nanoscale components such as waveguides, optical cavities, and photonic ...

At 2.0 mm by 2.0 mm by 0.65 mm and supports down to 1.6 V at typical operating current of 2 µA, the ambient light sensor can be used for a variety of battery-powered applications.

Here are some DIY LDR switch circuits available on our website and the web. LDR switches are used to switch a relay or other device when light are present or absent. LDRs or Light Dependent Resistors ...

This Circuit can compare the Light level in an area. It uses a PN Photodiode as the light sensor and IC CA3140 as voltage comparator. The circuit is ideal as the front end of burglar alarm circuits.

[Limpkin] designs circuits for a living. This board is one of his recent projects, and although his skills are light years ahead of our own experiences, he did a pretty good job of explaining how h… ...

When the ambient light levels drop far enough, the resistance on the reset pin increases, and the 555 timer breaks out of its reset loop. This causes the circuit to power on whatever is connected ...
