Abundant human energy powers electrical sensors

08 January 2018

Mechanical energy, which is possessed by everything that moves, is an abundant source of energy. Eiman Satti鈥檚 doctoral project has developed a footstep sensor that converts the mechanical energy of a footstep to electricity.

Converting mechanical energy to other useful forms of energy, and developing new devices that use mechanical energy to perform a task, can contribute to the energy supply.

The piezoelectric effect is one way of converting mechanical energy to useful electrical energy.
The video (link below) shows that many of the mechanical motions around us, such as handwriting and foot pressure, can be used to obtain useful electrical energy and signals.

The Physical Electronics and Nanotechnology research group is based at Campus Norrköping and led by senior lecturer Omer Nour.

Dysregulated immune cells cause silent inflammation after heart attack

People with narrowing of the coronary arteries have low-grade, uncontrolled inflammation in the body, even when symptom-free. The findings suggest that some immune cells drive a silent inflammation that may increase the risk of further heart attacks.

Participants in UN climate meetings want greater focus on implementation

UN climate negotiations are often criticised for moving too slowly. A new study published in Nature Climate Change examines what changes government delegates and other participants at the COP29 UN climate conference would like to see.

Eye problems after COVID-19 can now be explained

Mild COVID-19 can cause severe and long-lasting eye problems, according to a study from LiU. The study also explains why it has been difficult for sufferers to get help: the abnormal eye behaviour cannot be detected by standard methods.
