Researchers at the National Institute of Health’s (NIH’s) National Institute of Biomedical Imaging and Bioengineering (NIBIB) have developed materials that create electrical pulses when compressed by muscles in the body. “Piezoelectric materials such as ceramics and crystals have a special property of creating an electrical charge in response to mechanical stress,” says NIH. This technology has been used in ultrasound transducers and even in cell phones, and when used in the body show great potential to quicken the healing of bone fractures and help to manage chronic pain conditions.
