Shantanu Chakrabartty, a researcher at Michigan State University, is focused on the fundamental science behind self-powered sensors for health and usage monitoring. He says he is interested in the device’s “physics and in exploring new ways to sense and compute on the sensor.” Self-powered sensors developed by Chakrabartty and his collaborators may be attached to or embedded inside bridges, pavements, vehicles, rotating parts and biomedical implants. The devices can autonomously sense, compute and store cumulative statistics of strain rates without the aid of batteries. Find out more in this discovery.

The Division of Engineering Education and Centers in NSF's Directorate for Engineering (ENG) integrates disciplinary basic research and education conducted in other divisions of ENG and across NSF, into strategic frameworks critical to addressing societal grand challenges and to promoting innovation. Research included in the EEC portfolio spans both the physical and life sciences and engineering, from materials to new device concepts, subsystems, and systems.
A team of researchers from the University of Texas (UT) at Dallas has helped create flexible transistors that can grip large tissues, nerves and blood vessels without losing their electronic properties. These biologically adaptive, flexible transistors might one day help doctors learn more about what is happening inside the body, and stimulate the body for treatments.
A research team, led by biomedical engineers at Tufts University, has created tiny, biocompatible electronic devices, encapsulated in silk, that dissolve harmlessly into their surroundings after a precise amount of time. Dubbed "transient electronics," the new class of silk-silicon devices promises a generation of medical implants that never need surgical removal, as well as environmental monitors and consumer electronics that can become compost rather than trash.

'Smart implants' dissolve after healing
NSF Engineering Research Center for Revolutionizing Metallic Biomaterials is developing biodegradable metals for surgical implants
We all know that injuries happen and doctors sometimes have to use metal screws or plates to support broken bones while the bones heal. What if that implanted metal just disintegrated on its own after the injury heals?
A team at the NSF Engineering Research Center for Revolutionizing Metallic Biomaterials at North Carolina Agricultural and Technical State University is working to transform current medical and surgical treatments by creating "smart" implants. The major goal is to revolutionize metallic biomaterials to improve treatments for orthopedic, craniofacial, neural and cardiovascular ailments.
The National Science Foundation's (NSF) Engineering Research Centers are interdisciplinary, multi-institutional centers that join academia, industry and government in partnership to produce transformational engineered systems, along with engineering graduates who are highly skilled at innovation and primed for leadership in the global economy.
The research is this episode was supported by NSF award #0812348, NSF Engineering Research Center for Revolutionizing Metallic Biomaterials.
