Integrated Device Technology, a wholly owned subsidiary of Renesas Electronics Corporation, introduced a fully integrated all-in-one biosensor module for mobile and wearable devices. The smallest sensor of its kind, OB1203 Sensor module integrates a multi-channel light sensor (LS), a proximity sensor (PS) and a photoplethysmography sensor (PPG). This module comes in a tiny, optically-enhanced package at only 4.2 mm x 2 mm x 1.2 mm, and includes two LEDs, drivers, the sensors and a signal conditioning chip.
A key feature of the OB1203 is its antiallergenic glass cover, which allows it to be used in applications requiring direct skin contact. An additional advantage of the OB1203 is the ability to operate when covered with IR-inked glass, allowing product designers to almost entirely conceal the OB1203 for a cleaner, more aesthetically pleasing product design, says a press release.
A major application of the device is in smart phones or other mobile devices to enable brightness control of display panels. OB1203 can also determine proximity of nearby objects in order to support the deactivation of touch screen displays during phone calls.
The OB1203 comes with clinical-grade heart rate (HR) and SP02 algorithms, an easily customized Android app, and only requires power and three data lines to operate.
“Our OB1203 is the most advanced biosensor for front and upward facing applications, such as in mobile and wearable devices,” said Rudi Hechfellner, director of sensing technology at IDT. “Unlike other sensor technologies, the OB1203 can operate behind IR cover ink so that the sensor components are virtually invisible. This allows for a more pleasing industrial design and improved ergonomics for a better user experience. The tiny, fully integrated and calibrated all-in-one biosensor comes with a complete design toolkit and doesn’t require subject matter design expertise.”
