The problem with earbuds is that the battery life is not long enough. We free up space inside the earbud design by replacing sensors with our nanosensors. A typical MEMS sensor is 4mm3 but ours is only 1mm3 so we free up 3mm3 for every sensor that we replace with one of ours. So, three sensors replaced frees up 9mm3 for example and needs less PCB real estate. This can be used for bigger batteries or a supercapacitor to give Longer audio on the go™. Or the freed-up space can be used for additional features such as more sensors. These are of two types. First, sensors such as bone conduction sensors to detect the user’s voice so that noise cancelling algorithms provide better outgoing voice quality. Second, enhanced situational awareness so that the earbud can detect if it is in the ear, in a pocket or on a surface in order that it can automatically turn itself on or off to conserve battery life. Again, for Longer audio on the go™. Until now, designers were severely constrained on adding extra sensors as they would each take up valuable space inside the design. But our nanosensors can be easily added as they take up very little space. Multiple sensors on one die as in future, we will introduce products that combine several sensors on one die with hardly any increase in die size as the sensors are tiny and we can share most of the control electronics on the die. This gives the designer the choice to free up more space or add more sensors without much space loss.
