Current clinical trials – what’s up

Typical heaters are made very simple with a resistance that generates heat but can be complex to control. For example, see the design picture for a temperature controlled fan. There has to be a sensing element which needs to send an input to the control processor or element which in turns needs to regulate the…

There have been several studies that show that innovative trial design is required and in August 2018, FDA launched a program that would encourage novel clinical trial designs. They have issued guidance on novel trial design such as an expansion cohort which seeks to expand the clinical trial by allowing various cohorts into early phases…

Accelerometers are used very often in digital health devices. Let us try to understand them better but before that lets understand acceleration since that is what they measure. Acceleration:Let’s consider a runner in a 100m dash like the fast runner, Usain Bolt. He can rapidly accelerate from zero to nearly 27 miles per hour which…

Nicolelis’s lab has been working on the brain machine interface. The interface will obviously help many paraplegics but could be a boost for many neurological disorders. The lab has produced monkeys that can control objects using just their brains without any motor function. Recently, they created a mouse that though could not see infrared light…

There are many fitness monitors out there from Nike’s fuel band to Fit Bit. They all promise monitoring of activity in some form or another but none are very comprehensive.One company, promises better watches and sensors – Basis. Their sensors are equipped with not just accelerometer sensors but they also capture skin sweat secretion, heart…
