Piezoelectric is the property of a material to generate a voltage when mechanical force is applied to it. In contrast, the piezoresistive effect is the property of a material’s resistivity to change when subjected to a mechanical force. In either case, the mechanical force or stress can be compression, tension or a bending force. Ceramic […]

What is exponential technology?
In his presentation at the COMSWORLD2020 virtual event, Janusz Bryzek of eXo Imaging, described many details to support his premise of the exponential acceleration of healthcare problems. According to Bryzek, the convergence of exponential technologies or ExTech is accelerating the availability of healthcare to all. Exponential technologies include different types of health sensors, big data, […]
What is a Molecular Property Spectrometer sensor?
To measure and classify a wide range of combustible gases, NevadaNano has integrated multiple, complementary chemical sensors on a single silicon chip called the Molecular Property Spectrometer or MPS sensor. The chip’s patented array of micro-cantilevers with integrated piezoelectric sensing elements provides electrical actuation and sensing of resonance frequency. Monitoring resonance is a highly sensitive […]

What types of sensors are used in robots? Part 1 of 2
Fully functional human robots, such as those being developed by Boston Dynamics, need numerous sensors to simulate a variety of human and beyond human capabilities. For the human part, the sensors provide the ability to see, hear, touch and move. In general, industrial robots employ sensors for a variety of activities. Some sensors provide environmental […]
Customized transducer for differential pressure applications
The UTD20 is a customized transducer that features a piezo-resistive silicon sensor for differential pressure applications. Outputs are voltage or UART digital. Measuring ranges from 0 to 1.5 bar–the measuring range and zero set point can be set. Accuracy is < ±0.5 % of the nominal range (total performance) and temperature range is from -40 to 85° C. Other features include: • Sensor preconfigured […]
MEMS Microphone Employs Energy Harvesting
At the MEMS & Sensors Group Executive Conference in Scottsdale, AZ, Matt Crowley, the CEO of Vesper Technologies, demonstrates his company’s wake on sound MEMS microphone. The VM1010 prototype uses the piezoelectric MEMS microphone as a piezoelectric energy harvester for saving power with an always on voice mode. For more information, click here.
