Claimed to increase battery life by up to three times longer than other solutions on the market today, the low power Atmel SmartConnect XR and ZR modules consume less than 4mA in RX and less than 3mA in TX with 3.6V, and below 1.2µA in sleep mode.

Magnetic sensor reduces power consumption and processing time
Designed for portable devices, the MMC3630KJ, is a small, BGA package, magnetometer, from Memsic. The magnetometer integrates a monolithic, three-axis AMR sensor and signal conditioning ASIC and is based on the company’s proprietary technology. The BGA package measures 1.2 x 1.2 x 0.5mm. It has a range of ±30G range, and more than five times better noise level compared to other technologies, says the company. With 600Hz magnetic sensing bandwidth, the magnetometer provides better than 10 accuracy in eCompass applications. The design also has drastically lower system level power consumption and processing time, claims the company. There is also a self-degaussing feature, which can eliminate the output drift due to temperature change and residual magnetic from ambient magnetic field. The series also includes an interruption feature, which can be used for motion detection and data acquisition ready notifications to lower system-level power consumption. http://www.memsic.com
NFC security module protects wearable devices
Fitness trackers and smart keys to chains, watches or wristbands are increasingly including mobile payment functionality, needing them to be equipped with security and NFC technologies. Infineon has launched an NFC security module series in collaboration with Beijing-based Mobile Payment Solutions (MPS). It is claimed to “significantly” reduce design efforts by bundling an Infineon security chip with NFC antenna components and software on a small PCB footprint. The smallest module of the series measures only 4.0 x 4.0mm.
IDC Forecasts Worldwide Shipments of Wearables to Surpass 200 Million in 2019
Worldwide shipments of wearable devices are expected to reach 110 million by the end of 2016 with 38.2% growth over the previous year. According to the International Data Corporation (IDC) Worldwide Quarterly Wearable Device Tracker, an expanding lineup of vendors combined with fast-growing consumer awareness and demand will generate double-digit growth throughout the 2015-2020 forecast period, culminating in shipments of 237.1 million wearable devices in 2020.
