Specific Absorption Rate (SAR) Sensors
Semtech’s Specific Absorption Rate (SAR) sensors accurately discriminate between an inanimate object and human body proximity. The resulting detection from these sensing products is used in portable electronic devices, such as a smartphone or wearable device, to reduce and control radio frequency (RF) emission power in the presence of a human body. These touch sensing interfaces enable significant performance advantages for manufacturers of electronic devices with electro-magnetic radiation sources to meet stringent emission regulations criteria and SAR standards.
