A piezo disk transducer is a handy part for reproducing beeps and boops, and can also function as a rudimentary microphone. Being a piezoelectric element, it can also generate usable power. Enough to ...

Piezo discs have been around since the 1970s, and such cheap (and easy-to-handle) discs are widely used by avid electronic hobbyists and experimenting musicians all over the world. A piezo disk ...

Electromagnetic motors and drivers are have been optimized for more than 100 years. They can be found applications from toys to aerospace systems. With all their advantages, there are limitations such ...

This design was done to get a sealed keypad for very wet environments (in my particular case, showers for swimming pools). The keypad needed to be able to detect slight pressure on a stainless steel ...

Motion and positioning devices play an integral role in the life-science and medical engineering fields, fulfilling their many different requirements. The spectrum extends from simple low-energy drive ...

Inside each tile are the piezoelectric elements—thin discs of lead zirconate titanate—along with several solar cells and a lithium battery for storing power generated during the day. Researchers at ...
