Atomically-thin materials such as single-walled carbon nanotubes and graphene are prone to chemical attack because all of the constituent atoms are exposed. Here we describe progress from our lab in the synthetic creation of a tube-in-a-tube (Tube⁁2) semiconductor and their first applications in the electrical detection of small molecules and implications on biological sensing. A Tube⁁2 is equivalent...
We report here on a novel 3-axis MEMS accelerometer intended to meet the requirements of a high volume, very low cost sensor in consumer gaming and hand-held applications. In order to balance the performance and cost requirements of such applications, this device achieves 3-axis sensing with a single proof-mass. This accomplishment required significant process, device, and test design novelty. Because...
