The mechanical performance and lifetime of dynamic MEMS (micro electro mechanical systems) devices such as micropumps, micromotors, and micropositioners heavily rely on the bearing mechanism that enables motion per applied ...

A novel wearable blood pressure sensor scheme is presented. The design incorporates an array of piezoelectric transducers to transmit acoustic waves through the skin, and receive reflected echoes from an arterial wall. The ...

This paper presents a turbine-based microelectromechanical systems (MEMS) sensor for spirometry application. The compact sensor dimensions allow integration into smart wearable devices for mobile spirometry without a ...

We demonstrate that micro-scale rolling bearings exhibit friction and wear properties markedly different from their macro-scale counterparts. A microfabricated testing platform uses variable rolling element diameters or ...

The design, optimization, and performance characterization of turbine prototypes for the development of a Microelectromechanical Systems spirometer is reported. Four different turbines were designed based on large-scale ...

A linear non-resonant kinetic energy harvester for implantable devices is presented. The design contains a metal platform with permanent magnets, two stators with three-dimensional helical coils for increased power generation, ...

MEMS technology offers major advantages for the development of microphones including a small footprint, low power consumption, high sound sensitivity and bandwidth. Capacitive, piezoelectric, and inductive microphones have ...

Germination of Bacillus Stearothermophilus bacterial spores is being used as a marker in sterilization monitoring systems to verify the success of sterilization processes in healthcare facilities. Such systems mainly employ ...

This paper presents an in-vivo flexible pressure sensor that can be implanted around an artery for continuous measurement of blood pressure. Currently, in-vivo arterial sensor architectures rely on circular geometries fully ...
