Solid State Sound: A "Hot" Topic, Andrew Barnard

TechTalks

As seen with the latest iPhone 7 release, traditional audio components can now be a limiting factor in technology design. What if we could make a loudspeaker with no moving parts and virtually no weight? Carbon nanotube loudspeakers are such devices. They create sound using heat oscillations, as opposed to a moving diaphragm. They have the thickness of only a handful of carbon atoms, are flexible and stretchable. In this TechTalk I’ll discuss the carbon nanotube loudspeaker and the design challenges in maturing this intriguing technology.

Wearable Electronics, Human-Centered Monitoring, Ye Sarah Sun

TechTalks

Non-contact solution in wearable electronics: A conventional clinical system requires the use of wet electrodes that are in contact with skin using conductive gel to acquire physiological signals. Those systems can acquire high quality signals but may not be feasible for a long-term purpose due to the skin irritation and allergic contact dermatitis. The emerging of human-centered monitoring calls for alternative solutions. Recent technological advances enable capacitive measurement that can acquire signals through cloth or even with an air gap in wearable condition. In this TechTalk I will introduce the non-contact solution in wearable electronics.
