Scientists at Fraunhofer, a German research organization, are experimenting with applications of smart plastics— polymers impregnated with electronic sensors that can monitor body functions and respond to environmental changes. The Personal Health Assistant, a sensor-equipped wristband, has the potential to be used in a variety of health care and sports applications, such as detecting and notifying pacemaker patients of potentially damaging electronic interference or warning athletes of rising body temperature and impending dehydration. The wristband’s electroluminescent display automatically exhibits information. The Personal Health Assistant combines everyday products with cost-efficient electronics and demonstrates the possibilities for these smart materials in an innovative biometric system.
