In this post, we will be covering emerging technologies in the current Health Techs-scene that will change healthcare as we know it radically.
The technologies mentioned in this article can be generally categorized into three different groups (i) Diagnostics, (ii) Treatment, and (iii) Cybernetics (Human Augmentation).
I will be putting them into two sections. The ‘soon to come’ technologies and those that are on the horizon.
Within these groups, there are some reemerging trends:
Let’s dive in and take a look at the game-changers!
Smartphones and accompanying smartwatches…
Optogenetics is a biological method of controlling cells with light beams. The technique, developed by MIT scientists among others, allows for control of individual brain cells by general activation, inhibition, or even controlling intracellular processes.
As the name Optogenetics suggests, it’s a two-part process. Opto- comes from the Greek term “Optikos” or “Optics” in English meaning ‘the visible’, and refers to controlling the cells with light beams. The latter part, ‘-genetics’, comes from the genetic modification of said cells that is required for obtaining the light-sensitive property in the cells.
Scientists were inspired by naturally occurring proteins that are found…
Understand how a simple helmet can transfer your thoughts into computer commands
That’s a great question!
Classification of biomedical signals is essential in building Brain-Computer Interfaces (BCIs) to distinguish between different mental actions.
A higher resolution of signal classification is proportional to the number of mental commands a single BCI system can manage. Basically defining the band of the BCI user-interface (UI).
Without proper signal processing, recorded data from the electrical activity of the brain, won’t be of much use.
For the sake of simplicity, this article will mainly focus on signal processing for EEG recordings. (although much of it is transferrable)
EEG (and in general, other neural recording methods) give very small signals (low amplitude) and are often masked by other unwanted signals (artifacts). To extract signals representing brain activity, computational processing techniques can be utilized. This includes steps like signal scaling and applying different filters to the signal.
In short, signal processing is the computational manipulation of recorded signals to…
Signal acquisition is arguably the most important step in building devices that interact with the brain
In this post, I will discuss invasive recording techniques and the acquired brain signals that are used in invasive brain-computer interfaces (BCI). The cons and pros of invasive BCIs. And finally a glimpse into the future.
When building brain-computer interfaces and neurotechnology, the very first step is to acquire a signal from…
Writers, whether on tabloids & magazines, book authors, or bloggers here at medium, take science hostage in order to attract readers in the pursuit of financial gain. It’s problematic. Here’s why:
Not only are the scientific foundations of the claims that are made on thin ice, only backed by a single paper or two that themselves state their results as inconclusive and in need of further investigation, but the claims made are also often way out of proportion in comparison to what has actually been investigated.
Next, and perhaps more importantly (this is why I couldn't stop myself from this…
Neural engineering and neurotechnology are interdisciplinary fields utilizing a vast series of scientific fields including neuroscience, biomedical signal processing, nanotechnology, electrical engineering, clinical medicine, computer science, genetics, and the list go on…
The goal is to discover and engineer new ways of understanding, repairing, or enhancing the properties of neural systems.
Currently one of the most essential applicational objectives of neurotechnology is the restoration of damaged brain functions through interactions between external devices and the nervous system.
Research is being conducted to develop an understanding of the coding and processing of information in the brain: How processing is altered in…

The pandemic hit us all hard. Personally, I had the somewhat fortunate experience of being admitted to a psychiatric ward. Fortunate, because as a medical professional myself, this was a unique opportunity to witness the system from the inside. Most importantly I got the opportunity of talking with fellow patients, not in the setting of a medical interview as I usually do, but as a conversation between individuals. …
