At Sensors Expo 2018 in San Jose, CA, Jeff Sather, the vice president of Customer Solutions at Cymbet Corporation, explained the various formats for the company’s EnerChip thin-film, solid-state batteries. The wafer fabricated batteries have 5 µAH and 50 µAH ratings. The 5 µAH CBC005-BDC is a rechargeable 1.75mm x 2.15mm x 200 microns thick […]
How do you make an RF energy harvester even better?
For Powercast, whose Powerharvester receiver (PCC110) has been deployed in industrial and commercial systems for seven years, today’s answer is reduce the footprint and volume. The company’s new PCC114 receiver chip’s footprint (1 x 0.6 x 0.3 mm) is seven times smaller than the PCC110 (2 x 2.1 x 0.9 mm) and has 20 times […]
What is the current status of energy harvesting for wireless sensing systems?
Energy harvesting (EH) has been an exciting potential source to power wireless sensing nodes for well over a decade. As in many new technology areas, the hype frequently exceeds the capability of the technology, especially within the short term. While some projections have changed within the last few years, EH still has great potential for […]
What role does sensing play in bike-sharing?
They’re green. They’re yellow and many other very obvious colors. And, if they are in your town, they seem to be everywhere. Bike-sharing has become a high-volume business for companies with unusual names, like Ofo, Didi Chuxing, Mobike, LimeBike, and more. According to Ofo’s website, the process simply consists of: “Find it. Scan it. Ride […]
What new materials will create new sensors?
Materials with unusual properties are a starting point for creating new sensors. A company involved in products with complex material properties and electronics possibly has an edge over its rivals when it comes to discovering or creating new sensing technologies. For example, Continental, a tire maker and automotive electronics supplier recently used electrically conductive rubber […]
What new sensor applications are hiding in plain sight?
With all the new sensors available today that either (1) did not exist, (2) had less capabilities and/or (3) were more expensive just a few years ago, innovative engineers should be exploring new ways to use them. One way to do this is sensor specific: with sensor X available at an affordable price, what can […]
How can you make batteries last forever in a wireless sensing system?
At Sensors Expo 2017, Geoffroy Gosset, CEO and founder of e-peas, explains how a variety of energy harvesting techniques and low power solutions that his company supplies can answer this question. Using the company’s power management ICs (PMICs), systems can be designed that run ARM processors continuously at low frequencies and draw less power than […]
How do you accelerate an energy harvesting design?
One of the more common techniques for accelerating designs and avoiding unexpected design problems involves software tools. For energy harvesting (EH) applications, Mentor Graphics on-line modeling and simulation platform called SystemVision, a cloud-based design system, provides component/system suppliers and users the basis for a new EH design tool. Since many designers are intrigued by the […]
How can energy harvesting be used in industrial applications?
Energy harvesting (EH) or converting renewable or existing sources of energy to electrical power can occur with several sources including light, heat, and motion providing the input. Photoelectric, thermoelectric, piezoelectric and electrodynamic techniques are well-known and often used to power sensing nodes that transmit data to a central controller. Depending on how much light is […]
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.
