By reading different values from the sensor, we can detect if is it light , dark or a value between them. Another element that we are going to use on this experiment is Piezo Buzzer.

Moreover, environmental concerns over the use of lead-based piezoelectric materials have motivated the need to develop and utilize lead-free piezoelectric nanostructures for sensors 22.

A research team led by Dr. Lim Sang-kyu in DGIST's Department of Energy and Environmental Technology has developed a smart fiber sensor that can detect natural disasters such as landslides in real ...

Piezo Trigger Switch circuit described here is a microcontroller-compatible shock/impact sensor switch module works on 5VDC supply. The whole circuit can be assembled on a 5×7 cm common circuit board.

Professor Lee’s team has developed the wearable piezoelectric blood pressure sensor by transferring a highly sensitive, inorganic piezoelectric membrane from bulk sapphire substrates to flexible ...
