Biomedical engineering students at Johns Hopkins University (www.bme.jhu.edu) have invented an unobtrusive device to measure the force doctors or midwives use when delivering a baby. An electromyographic instrument, the device can measure electrical impulses in the muscles of the user's forearm. A wireless transmitter then sends the data to a computer across the room for assessment.
A new fixings and fastening system for assembling structural, load-bearing composite components promises 54% better adhesion, plus less weight and better mechanical performance than current composite fixing designs.
