nano-Digitisers

We coined the term ultra-high piezoelectricity





We are digging at the atomic length-scale to enable you to covert energies

Can't think of what is of use... 

Here are some examples.









<Clean energy production>

Piezoelectricity is one of the least explored energy harvesting. However, it is a potential route to scavenge energy for implantable biomedical devices.

<Fast computing>

Single-electron switches or transistors are future of computing.

<Mechanical sensing>

From mechanoelectrical sensing of biological phenomena to pollution sensing and diagnostics.

<Precision instrumentation>

Electromechanical actuation with nanometric resolution is key for many fundamental scientific experiments and industrial technologies.

<Precision optics>

Quantum wells are widely used for single-photon emission and single-photon detectors in quantum optoelectronics.  The modern bright displays  uses quantum-dot light emitting diodes aka QLED displays for pure basic colours.
