background and aims. digital imaging continues to gain acceptance in dentistry and video display used for this becomes important. the aim of this study was to assess the influence of the display monitor on observer performance on caries detection. materials and methods. artificial enamel lesions were created in 40 extracted teeth at random using 1/4 and 1/2 round burs. teeth were mounted in den...

Energy harvesting is a new promising research area for portable electronics. Portable electronic devices have been typically limited by the finite lifetime and size of the internal batteries. This has been a constant conflict and tradeoff between battery size and device capabilities. For instance, cardiac pacemaker lifespan is mostly limited by battery size, which occupies at least half the ava...

Electroactive soft actuators and bioinspired artificial muscles have received burgeoning interest as essential components in future electronic devices such as soft haptic-feedback systems, human-friendly wearable electronics, and active biomedical devices. However, important challenging issues including fast response time, ultralow input power, robust operation in harsh environments, high-resol...

Neuroprosthetics is a fast-growing area that brings together Biomedical Engineering and Neuroscience and seeks to interface the neural system directly to prostheses. The main goal is to restore motor, sensory, and cognitive functions. Neuroprosthetics is electrical stimulation technologies that replace or assist malfunctioned neuromuscular systems and attempt to restore normal body functions. T...

Recently developed classes of electronics for biomedical applications exploit substrates that offer low elastic modulus and high stretchability, to allow intimate, mechanically biocompatible integration with soft biological tissues. A challenge is that such substrates do not generally offer protection of the electronics from high peak strains that can occur upon large-scale deformation, thereby...
