Employing low-frequency noise can help electric vehicles stand out in busy environments
One of the many benefits of electric vehicles is that they are much quieter than traditional gasoline-powered vehicles. In some cases, though, they are too quiet. Automakers are required to design ...
Abstract: This study investigates the use of 5 kHz piezoelectric ceramics (PZTs) for real-time, in situ monitoring of glycerol concentration during biodiesel production. A matched pair of PZT in a ...
Researchers have made a major advance in quantum computing with a new device that is nearly 100 times smaller than the diameter of a human hair. Subscribe to our newsletter for the latest sci-tech ...
HydroModem is a Bell 103 modem implementation to decode data from an always-on underwater hydrophone. Designed for low-power microcontrollers such as AVR ATmega328P, it can listen underwater long-term ...
Abstract: This paper reports a novel composite high-frequency vision-based tactile sensor with an embedded transparent MEMS-based piezoelectric module. Taking advantage of the transparency of the ...
