One or more biometric indicia, such as fingerprints, voice prints, retinal scans, and facial features, are often used to identify or authenticate the identity of a user seeking access to a given resource. Cardiac muscle is myogenic and is capable of generating an action potential and...

Researchers from the USC Viterbi School of Engineering have developed a flexible, energy-efficient hybrid circuit combining carbon nanotube thin film transistors with other thin film transistors. The hybrid could take the place of silicon as the traditional transistor material used in...

A wireless system uses the same power as a cell phone to safely transmit energy to chips the size of a grain of rice. The technology paves the way for new "electroceutical" devices to treat illness or alleviate pain.The central discovery is an engineering breakthrough that creates a...

A software application detects the heart rate of an individual by using a real-time video stream from a common camera connected to their computer. This involves no contact between the user and the camera, or calibration between individual users. NASA’s...

Researchers at MIT’s Computer Science and Artificial Intelligence Laboratory have developed a new algorithm that can accurately measure the heart rates of people depicted in ordinary digital video by analyzing imperceptibly small head movements that accompany the rush of blood caused by the heart’s...

Several technological enhancements have been made to METI’s commercial Emergency Care Simulator (ECS) with regard to how microgravity affects human physiology. The ECS uses both a software only lung simulation, and an integrated mannequin lung that uses a physical...

This device provides non-invasive beat-to-beat blood pressure measurements and can be worn over the upper arm for prolonged durations. Phase and waveform analyses are performed on filtered proximal and distal photoplethysmographic (PPG) waveforms obtained from the brachial artery. The phase analysis is used...

Current transcranial color Doppler (TCD) transducer probes are bulky and difficult to move in tiny increments to search and optimize TCD signals. This invention provides miniature motions of a TCD transducer probe to optimize TCD signals.

A team led by Ki Chon, professor and head of biomedical engineering at Worcester Polytechnic Institute (WPI), has developed a smart phone application that can measure not only heart rate, but also heart rhythm, respiration rate and blood oxygen saturation using the phone's built-in video camera....

A Fiber Optic-Based Integration System (FOBIS) has been developed that may be capable of in-situ, real-time biological monitoring, and is based on a single fiber optic system. A compact, multi-functional device, the FOBIS incorporates three working units (a Micro-Flow Cytometer, a Micro-Photometer, and a Micro-Sensor)...
