How many MEMS have you used today? Have you used a Smartphone? GPS? Activity tracker? Gaming system? Car? Printer? Then the chances are that you have used many of them in the form of motion sensors, pressure sensors, microphones, inkjet printhead or other.
To be fair, MEMS can’t sing on their own. But with USound, we’re making the world’s first miniature piezoelectric MEMS (Micro-Electro-Mechanical Systems) actuators for smart audio systems in portable devices. In contrast to MEMS devices that SENSE (motion/inertia, pressure, temperature, etc.), this effort will produce MEMS devices that ACTUATE, vibrating at frequencies in the audible range like the diaphragm on a traditional loudspeaker. This team effort uses ST’s industry-leading thin-film piezo-electric (TFP) technology to improve scalability and cost while lowering power consumption and heat dissipation in hearables and smartphones devices. And with USound’s unique technology, we do this with uncompromised audio quality.
In fact, USound’s piezo-MEMS devices offer unprecedented mechanical precision that improves audio reproduction fidelity and device reliability. The first-of-its-kind device, USound’s MEMS “Moon” speaker targets earphone applications, bringing superior performance to the audio world at a competitive price. ST and USound will be showing and demonstrating the technology at Mobile World Congress February 27-March 2. If you’re in Barcelona, stop by ST booth A61 in Hall 7 and hear more.
We’re looking forward to hearing more about these MEMS actuators when they ship in consumer products late this year!
