Current sensors, audio amplifiers, op amps, analogue switches, and battery gas gauges from STMicroelectronics are designed to be a set of building blocks for wearable applications. Examples of devices suitable for wearable applications include the single, dual, and quad op amps, such as the OA4NP33 quad low-power op amp, that offer a low-power typical consumption of just 580nA/channel (at 1.8V power supply), suitable for functions such as sensor signal-conditioning in battery-operated wearable devices.

GNSS antenna supports satellites
The CAM-M8Q GPS/GLONASS/BeiDou/QZSS antenna module integrates a u-blox M8 satellite receiver IC, SAW filter, LNA, TCXO, RTC, passives and a pre-tuned GNSS chip antenna. The surface mount device measures just 9.6x14x1.95mm, and offers high-sensitivity, high jamming immunity and concurrent GNSS operation (GPS/GLONASS, GPS/BeiDou, or GLONASS/BeiDou) for accurate satellite positioning anywhere in the world, claims u-blox.
Module is claimed to be world’s smallest Bluetooth Smart
Designed for the Bluetooth 4.0 low energy (LE) specification, or Bluetooth Smart, the SESUB-PAN-T2541 Bluetooth 4.0 LE module is claimed to be the world’s smallest module. The footprint is 4.6×5.6x1mm.
Motion sensors and microcontrollers make a splash in sports watches
Miniature motion-sensing and data-processing chips from STMicroelectronics are used in the latest Swimovate sports watches, the PoolMateLive. The automatic training aid is an intelligent water-proof watch that provides information about a swim and stores the data for analysis.
