  • Bioimpedance device

    Bioimpedance device

    Bioimpedance is the resistance of any biological tissue between two defined points. Usually the two points may be the two extremities – for example the hand and the foot. This has been measured for many years and a single value of resistance called bioimpedance has been used in many areas to estimate percentage of fat,…

  • Brain to brain communications

    Brain to brain communications

    Brain to brain communications or brain to computer communications are tough to execute. However, one consortium of scientists at Braingate have achieved the communication between two people that are connected with a sensor implanted in their motor cortex. The unique part about this communication was that it was implemented through methods more often used in…

  • Digital health: Heat or cool your body quickly

    There have been many consumer digital health devices that aim to measure complex parameters and report. They start from simple as activity measure to complex ones like EEG. Then there are devices that alter some human physiology by providing therapeutic doses of electricity or some other complex signal.Many of these devices have been referred to…

  • Current clinical trials – what’s up

    Most current clinical trials in the US are tracked through clinicaltrials.gov website. If we look at the top 10,000 titles and do an analysis of the most commonly used words that are utilized in the titles then you get an interesting perspective on what are the studies that are being done currently.Note that many trials…

  • One Danger of working with digital health companies

    There was once a company that engineered a very good sensor . This sensor measured whether you were sitting up straight in your chair or slouching. If you slouched it sent a small vibration and reminded you. The market need that they targeted was that people needed to sit straight for their back and this…

  • Innovative clinical trial design

    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…

  • Measuring gait

    Recently we have been studying human walking and trying to understand its various components.Human walking seems so simple as shown in the video below by phsiotutors, but is a very complex activity. It involves multiple muscle movements coordinated into a seamless activity that is a balancing act on two legs accompanied by forward motion. Walking…

  • Pictures and photo as paradigm for medical data

    There has been significant discussion on who owns medical data. The hospital or service that collects the data or the patients themselves? Then there are questions about how do we manage the data – who manages the data? Security issues? Exchange and storage? And more importantly business issues on who commercializes the data – who…

  • Wearable for digital health requires communication strategy: IOT and LORAWAN

    Wearable for digital health requires communication strategy: IOT and LORAWANAn ideal wearable digital health system has these 3 top requirements:1.    Simple – No complicated setup and automated data collection procedure 2.    Long measurement – Ability to collect data over extended periods3.    Actionable data that is securely stored or sent to a databaseDigital health technologies have…

  • Analyzing wearable device activity data

    Many research studies have incorporated the use of wearable devices into the study to measure the activity of humans in response to a variety of interventions. There are grossly three parts to that process:1.    Selection and adoption of the activity monitor – accelerometer or gyroscope based devices2.    Process for collection of the data – supervised…
