What’s new in temperature testing for COVID-19?

October 13, 2020 By Randy Frank

When COVID-19 appeared earlier this year, the first wide-spread testing to detect if a person had the disease involved temperature. In contrast to other invasive approaches, the need for improved temperature testing prompted a few companies to investigate and then develop their own approach. Dermal Photonics Corp. solution was a wearable smart thermometer called NIRA […]

How is self-powered clothing doing?

July 27, 2020 By Randy Frank

If you’re interested in the information and convenience that a wearable product can provide, you probably do not want to worry about how it gets its energy or when recharging is required and certainly do not want to change batteries. You just want to get uninterrupted information. One company built on offering invisible wearables has […]

How can backscatter communication improve wireless sensor networks?

February 22, 2020 By Randy Frank

As an integral part of the Internet of Things (IoT), wireless sensor networks (WSNs) are projected to have rapid growth. According to the “Wireless Sensor Network Markets” report, by 2023, there will be 3.4 billion annual WSN chipset shipments worldwide up from 1 billion in 2018. If the WSNs only use batteries for their power, […]

Is the energy in energy harvesting really free?

April 11, 2019 By Randy Frank

Of course. However, the conversion process to get useful electricity certainly is not. Also, several design considerations must be taken into account to ensure a system’s success. This includes thinking differently about power consumption. With all of the wireless communications applications expanding in consumer, commercial and industrial applications, the power must be achieved without connecting […]

How can you harvest RF energy?

December 15, 2018 By Randy Frank

At Sensors Expo, Eric Biel, an engineer from Powercast Corporation, explains how radio frequency or RF energy can be used in energy harvesting applications. RF wireless power transmitted by the PowerSpot transmitter is received by two receiver sticks with LEDs. The TX91503 PowerSpot transmitter broadcasts an RF signal in the unlicensed 915 MHz industrial, scientific […]

What’s new in supercapacitors for energy harvesting?

September 20, 2018 By Randy Frank

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?

September 17, 2018 By Randy Frank

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 […]
