Wearables
For years, we've tracked everything from our steps to our sleep.
Wearables can monitor heart (HRV), temperature, VO2…
Atlas
Atlas is a tiny device, worn discreetly behind the ear, measures electrical brain activity in real time.���It took five years of R&D, a breakthrough in sensor technology and hardware.�
A brain wearable for everyone and
everyday life.�

Brain and technology
Small (<500 uV) time-varying electrical signals generated by complex network of neurons.
New tools – New materials – New technology
Kampff, A. R. (2013).
Neurotechnology in my life
Phd project: silicon-based neural sensors for
large-scale, high-density extracelular recordings,
inside the brain (invasive, implant)
Pos-doc project: polymer-based neural sensors for
extracelular recordings, outside the brain (less invasive, ECoG)
Occam project: wearable, polymer-based sensors for extracelular recordings for everyone and everyday (non invasive, EEG)
PhD project: why?
Extracelular recordings inside the brain for measuring with precision individual neurons electrical activity.
Orientation of light slit
Neuron signal
Hubel and Wiesel, 1962
Hubel, 1957
PhD project: How?
Validate and achieve the full potencial of the tool by using micro and nano-technology, CMOS-based sensors.
Dimitriadis*, G., Neto*, J. P, … Kampff, A. R. (2018).
PhD project: challenge
Implantable neurotechnology triggers a body response and can damage the tissue, wich leads to failure over time.
Lopes, G, … Kampff, A. R. (2023).
Less invasive, ECoG
Transparent and ultrathin ECoG sensors, recordings with direct visualization of neurons.
Neto, J. P, … Barquinha, P. (2021).
Trêpo, I., …., Neto, J. P (2023).
Neurotechnology for everyday
Able to collect great EEG quality data in real world and motion conditions and to do so using a device which is sleek, sexy and discrete�
Challenge for hardware
Nunez & Srinivasan (2009).
Challenge for sensors (team)
New materials and Nanotechnology
Nano-based electrodes patented with high electrical and mechanical performance, biocompatible and conformable over long-wear.
Signal recorded with our sensors (and hardware):
High-quality EEG in naturalistic motion conditions that break conventional systems.
