A Vibration Chip is Installed at the Back of the Midsole to Protect Workers From Vibration-Induced White Feet
In order to protect workers from vibration-induced white feet a vibration chip is installed at the back of the midsole.a vibration chip is installed at the back of the midsole It transmits a signal to the shoes via a haptic driver IC and generates mechanical noise in the plantar foot, mimicking a vibrating road surface. The chip also allows the user to control a variety of settings such as speed and direction of the vibration.
This paper investigates the effect of different shoe sole material on the vibration transmissibility in the frequency range where the toe resonance occurs (90-150 Hz). The results obtained show that no single material is able to reduce the transmission of high frequencies to the toes. In fact, most of the tested materials worsen the vibration exposure of the toes with respect to barefoot conditions in this frequency range, evidencing that current standards are inadequate for the evaluation of working shoes. A poor correlation between subjective evaluation of comfort and the vibration transmissibility is also evidenced, pointing to the need to introduce new standardised tests for footwear.
Vibration sensor manufacturers produce sensors that can measure vibration and transmit the information to a computer. These are primarily used for monitoring and analyzing vibration levels in the workplace. However, these sensors have their limitations. These include the fact that they do not provide a very precise reading and are vulnerable to climatic factors such as humidity, temperature and wind speed. Moreover, they cannot respond quickly to vibration changes due to dynamic loads, which are often caused by moving objects such as vehicles or machines.
Researchers from the Politecnico di Milano and Laurentian University in Canada have developed an innovative system for a vibrating shoe insole that delivers a subsensory mechanical noise signal to the plantar side of the foot during walking. This can reduce the variability of the mean toe clearance (MTC) of the foot, thus reducing the tripping risk. The system is composed of a vibrating insole, a noise generator and tactors.
Physicists have made mechanical vibrations on a chip behave like electrons in a magnetic field, curveing their trajectories. This can unlock new ways to manipulate sound waves and the information they carry, according to a study published in Nature Nanotechnology.
A new device could help doctors diagnose and treat patients with balance disorders. It consists of an insole that provides a vibration-based mechanical signal to the foot, improving balance in healthy young and older people as well as in patients with stroke and diabetic neuropathy. The insole would contain electronic devices called tactors to deliver a mechanical noise signal to the plantar foot, and a noise generator to provide the input signal. The tactors can be electromechanical or piezo actuators, and are powered by the haptic driver IC. Ideally, the insole would be combined with a sensor to measure acceleration to allow for a more accurate diagnosis and treatment of balance disorders. The research was supported by the European Union's Horizon 2020 programme. The project leader, Prof. Alessandro Fassini, is director of the laboratory of Advanced Technology for Biomedical and Health Applications at the Politecnico di Milano.
