At Sensors Expo 2018, Pierre Mars, head of the applications team at Cap-XX, a supercapacitor manufacturer from Australia, explains the supercapacitor demos in their booth. Using a 800 mF supercapacitor provides the energy to power a 2.9V near-field communication (NFC) 13.5 MHz sensor puck from Silicon Labs. With the charged supercapacitor (above 2.6V) the unit […]
What’s new in batteryless sensing?
To solve the problem of replacing batteries in ever-increasing wireless sensing applications in the Internet of Things (IoT), PsiKick has developed proprietary sensors called Smart Sense Nodes (or S2Ns) that employ ultra-low-power digital and RF circuit technologies. The S2Ns are powered by energy harvested from heat or indoor lighting that eliminates the need for a […]
What’s new in solar energy harvesting for sensors?
At Sensors Expo 2018, Ben LeNail, Director of Business Development at Alta Devices, a maker of thin, flexible solar photovoltaic cells for energy harvesting, provided an update on the company’s technology, its applications and energy harvesting solutions for sensors. The company’s specialty photovoltaic cells are ultra-high efficiency devices. Alta Devices has held the world record […]
What’s new in thin-film batteries?
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 […]
