A Piezoelectric-triboelectric Heel Charger for Power-on-the-go

A heel charger that uses a level mechanism and a mechanical SSHI boosting circuit to provide electrical energy Background: Running out of battery power often results in life-threatening situations, whereas backup batteries are large, heavy and hazardous. In efforts to treat this unreliable aspect, proposed is an energy harvester. This is a clean...

Chopped Passive Infrared Sensor Apparatus and Method for Stationary and Moving Occupant Detection

Additions of multiple different elements to improve current PIR sensors. Background: Passive infrared (PIR) sensors are used in a variety of applications. They work by using the pyroelectric effect: a change based on the temperature modifies the positions of the atoms. However, because voltage is generated by pyroelectric materials, conventional PIR...

A Novel PET Imaging Agent for Diagnosing Bacterial Infections

A PET tracer, [18F]F-PABA which is taken up only by bacterial cells thus making it specific for diagnosing infection. Background: Bacterial infections such as those of prosthetic joints, bones (osteomyelitis) and heart valves (infective endocarditis) are difficult to diagnose and treat, and are a major cause of mortality, morbidity and health care...
