The Si1143/44 solution combines a high precision optical sensor, an LED source, a proprietary algorithm, and a low power MCU to deliver the industry’s lowest power, dynamic heart rate monitoring (HRM) solution. Target markets include fitness bands, smart watches, and consumer health applications.
In addition to low power, the Si1143/44 solution provides performance that rivals the traditional chest strap. The Si1143/44 uses a single green LED, which allows it to be packaged in an exceptionally small package (2.9 mm x 4.9 mm.)
This performance is delivered at a fraction of the cost of the best optical solutions in the market.
