High-performance flexible thermoelectric modules based on high crystal quality printed TiS2/hexylamine

Printed electronics implies the use of low-cost, scalable, printing technologies to fabricate electronic devices and circuits on flexible substrates, such as paper or plastics. The development of this new electronic is currently expanding because of the emergence of the internet-of-everything. Altho...
