Tapani Ryhanen, CTO, Emberion

Tapani Ryhänen has been working on different nanomaterials and their applications in various sensors and electronic components since 2007.

‘During the past 10 years, my team has systematically focused on creating novel image sensors and cameras based on colloidal quantum dots and 2D layered materials, especially graphene. Expanding the wavelength range of affordable image sensors to SWIR and MWIR will open numerous applications in industrial machine vision, spectroscopy and eventually in consumer applications,’ said Ryhänen.

This will be possible using lower cost manufacturing technologies and novel materials, he predicts. ‘We will see SWIR and MWIR sensors in environmental measurement, as enablers of circular economy and various industrial measurements.’

While Ryhänen believes the stability of nanomaterial-based image sensors will improve gradually and that they will be robust over time and in challenging operating conditions, he said ‘scaling up the production of nanomaterial-based image sensors requires a lot of effort and investments’.
