Printed electronic technology such as RFID antennas and tags are predicted to revolutionize sectors of the portable electronics industry, reports Electronic Products & Technology. To process applications, many RFID draw on thin, flexible carbon-zinc batteries, as a primary power source. The batteries are not rechargeable, but they are relatively low in cost and safely disposable.
Conventional button or coin cell batteries contain lithium, mercury or other potentially hazardous chemicals. However, the thin printed batteries used in powering RFID make use a lead-free, carbon-zinc. They contain no toxic substances and meet full compliance of the European Union’s Restrictions on Hazardous Substances Directive.
RFID-enabled time and temperature monitoring systems are being increasingly used in the food industry as a means to ensure consumer safety, maintain quality control and reduce waste. One such system now on the market uses a sensor probe and battery-powered “smart” card to ensure cold chain compliance across the supply chain.
Similar systems are also useful for distributors of temperature-sensitive pharmaceuticals, as an increasing number of new drugs being developed require strict temperature control to maintain their efficacy.
Battery-assisted passive RFID is said to extend read ranges and memory capabilities, as well as increase tag readability and accuracy – especially in applications that involve liquids and metals.
