Sensaris introduces the first dual mode Bluetooth solution for blood glucose and
temperature data management.

People dealing with diabetes want to leverage mobile technologies to improve their daily lives while keeping the glucometers they are familiar with. Ease of use, cost of consumables and measurement accuracy are key factors in device selection.

Likewise, when it comes to smartphones, a large majority of blood glucose meter users indicate that there is a growing need to have solutions compatible with the widest possible variety of smartphones and tablets, not just the latest models. To fill this gap, Sensaris is introducing the first dual mode Bluetooth/Bluetooth Smart interface for diabetes management applications. Blood glucose data can now be easily managed from smartphones, not only to improve reporting to health care professionals, but ultimately to lower glycemic variability for patients and thereby reduce the number of hypoglycemic events.

Along with providing connectivity to the Lifescan One Touch Ultra 2 glucometer (one of the most accurate device for veterinary blood glucose measurements), a non contact infrared thermometer can also be used with the same dual mode interface for medical grade temperature measurements.

The “2for2” device (2 Bluetooth technologies for 2 measurements) comes with an API so that developers can quickly integrate glucose and temperature data into their own mobile phone applications for iOS or Android based devices.

Dr Michael Setton of Sensaris explains that “By using the Bluetooth Low Energy technology and combining with existing medical devices Sensaris has made the existing technology more patient friendly. The first combined device will be available for the veterinary market and will migrate to human use when FDA and CE certification are obtained. This is an important strategic step for patients as a December 2013 study by Allied Marked Research indicated that the blood glucose meter market is likely to capture the lion’s share of the world mHealth market in the next few years.”

Sensaris intends to extend the 2 for2 to several glucometer brands and to integrate other physiological measurements for better chronic disease management.

We looked at various systems, but they did address mostly messaging and were often far too costly to deploy or suited just for one country. (See for example US driven Direct Project).Y3 enables us to design mobile centric solutions which are both interoperable and future proof. Yobidrive’s CEO, François Vaille, describes their vision pertaining to the use of PKI for Securing The Internet of Things:

Yobi Drive’s Blog: Securing the Internet of things.

Let’s take a pulse Oximeter: raw saturation data has to be cleaned from non representative measurement points, added to a live data set, but also aggregated day by day… the real, meaningful data is not the raw data from the sensor. Primary data is the saturation, metadata can be location, date and time, authorized readers, sensor health… context could be “live data” or “archived”.

All those operations being managed in a Y3 context transition, the data is encrypted with the keys of the sensor immediately after all those transforms in the blackboxed Y3 API, and stored ready for use by mHealth visualization apps. Those apps access the meaningful sensor data after door opening ( so decryption enablement ) by the end user himself, in the same way than he accesses protected shares in YobiDrive FX.

IoT is a very simple and natural application of contextual storage, immediately adding intelligence to the raw nature of – not so – smart things.

Whether used for chronic disease management, in hospitals or real time monitoring during emergency transport, security and trust are always among the top requirements for our customers. Even in a growingly fragmented and diverse mobile environment, once healthcare providers have agreed on PKI certificates revocation checking, one of the last barriers to adoption will have been addressed ; patients at the center of the healthcare system, will be able to use the m-Health Internet of Things on a daily basis.

We released an application for Android phones to measure peak flow values using Bluetooth data transmission. Peak flow meters are simple devicex measuring how quickly air is expelled from one’s lungs and are used in daily life for asthma monitoring. Peak flow values of 50% – 80% of a person’s best results are a sign of a moderate asthma attack, while values below 50% are a sign of a severe attack.

As part of a management plan, having regular readings will help asthma sufferers better control their disease, manage their medication or even act hours-sometimes days-before early signs of asthma attacks appear.
Our growing application portfolio opens new doors to better understanding of correlation between air quality/personal pollution exposure and physiological effects.

Sensaris releases ZAO, an all-in-one biomedical device for m-health applications.

ZAO is a all-in-one biomedical device for mHealth, disaster relief, wireless hospitals or innovative homecare uses. It communicates with mobile phones, tablets or access points and leverages cloud technologies for unprecedented applications. In a single package the following functions are provided:

  • - Pulse oximeter
  • - Blood pressure monitor
  • - Thermometer
  • - Glucometer interface
  • - With a WiFi module

To use ZAO, a doctor, a nurse or even a patient selects the function to be used and then starts measurements . Thanks to mobile and web based applications, ZAO displays the data either just locally or sends it securely to a distant server.


Working with doctors and nurses over the last 10 years, Sensaris realized that providing wireless devices was not enough. They needed a single wireless unit to perform essential and vital basic measurements: oxygen saturation, heart rate, body temperature, blood pressure, blood glucose. Something that like a stethoscope they can always carry, a device which fits in a pocket. Small size, ease of use and ruggedness are crucial for telemedicine applications.

Patients also told us that instead of having to learn to operate a variety of devices they wanted a simple to use, reliable unit compatible with their phones, internet gateways or TVs.

So with the help of mHealth specialists and ER doctors we took the various stages of ZAO through tough field testing and we are now proud to introduce the result of this team effort.


We could have added a screen on ZAO to simply give results directly on it. But we chose not to because we strongly believe that a lot of applications can be developed around wireless technologies and networks. It is all about seamless experience and users using different interfaces through the day: phones, tablets, PCs, TVs. ZAO delivers vital information in real time at the point of care no matter when or where.
Two way communication over IP also provides field users with instant access to expertise. Moving data rather than patients is always more efficient.


The patent pending ZAO is the first device with 5 key healthcare functions compatible with both Android and iOS based devices (even satellite phones for remote area telemedicine).

Connectivity to plug computers enable easy deployment and connectivity to hospital Ethernet or WLAN networks.
Entreprise level security and data encryption.

Compatible with mobile broadband access for disaster emergency response.

Interoperability with existing health systems through IEEE 11073 data transcoding.

Patent pending

Recently an interesting article indicated that a low cost Android from Huawei is already used by 350 000 kenyans.

“It seems like just yesterday when only the slickest kid on the block had a smartphone, but now,this revolutionary gadget is selling like hotcakes in the developing world. Earlier this year, the
Chinese firm Huawei unveiled IDEOS through Kenya’s telecom titan, Safaricom. So far, this $80 smartphone has found its way into the hands of 350,000+ Kenyans, an impressive sales number
in a country where 40% of the population lives on less than two dollars a day. The IDEOS’s success in this market firmly establishes the open source Android as the smartphone of the
people and demonstrates how unrelenting upswings in price-performance can jumpstart the spread of liberating technologies. Thanks to low-cost Androids, the geographically-untethered
smartphone is here to stay, and it simply cannot be stopped.”

In June 2011, Huawei and Safari Telecom signed a memorandum of understanding for technology transfer with 3 kenyan universities. Dr Bitange Ndemo, the Permanent Secretary in the Ministry of Communications indicated that he sees 90% of phones being smartphones in the next 2 years.

That same month, , Safaricom and Telkom Kenya announced they were embedding health services into their product offerings. It is not an altruistic endeavour however, as both companies hope the move will see their profit margins increase, after prices wars have devastated the countries telecom sector in recent months.
Much of the focus will initially be on rural areas in the country through the virtual clinics, which the telecom companies said would bring in “modest” consultation fees. The mobile operators claim users will make huge savings on money spent on travel and logistics associated with hospital visits.

Safaricom’s Health Presence will be equipped with facilities to read a patient’s vital signs – including temperature, pulse rate, blood pressure and respiratory rate. On the other end, the doctor on call will be able to read the vitals on a computer and together with the patient’s narrative, is able to give a diagnosis and prescription or refer the patient to a health clinic.
The e-health centres will be housed in digital villages set up by Safaricom. It has put up 800 digital villages and plans to put an additional 5,000 by end of this year.
Sylvia Mulinge, the general manager of Enterprise Business Unit at Safaricom, said
“In the first year, we will have 30 per cent of the digital villages equipped with the health presence facility,The project is meant to take affordable and quality health care to the common person. One should be able to consult a professional medical practitioner at under $2 (Sh168). This would in ordinary circumstances cost one in excess of Sh2, 000, when one factors in travel costs and other logistics.”

Adapting our products and services to meet new challenges.

Emerging countries are quickly embracing mhealth technologies and it is not a coincidence if the GSMA first mobile health Summit took place in South Africa in June.
Shipments of budget Android phones priced at around the US$150 mark numbered just 2.5-3 million units in 2010, the vast majority of which were split between ZTE (ZTE Racer model, review and specs here) and Huawei (IDEOS, review here) .
Sales of such phones are expected to grow to more than 20 million units in 2011. Huawei plans to ship between 12 and 15 million Android powered devices this year,At a time when healthcare budgets are being re-examined, it is clear to us that mHealth can contribute to improving quality care without requiring substantial investments. To encourage this move, we have ported all our mobile health applications to this IDEOS phone: software packages for our biomedical devices in the Senspacks (thermometer, glucometer, blood pressure monitor, pulse oximeter) are all available now for such entry level smartphone. Granted the low resolution takes some getting used too after using higher end smartphones,the screen keyboard is tiny and it can be annoying to type SMS messages, and more annoyingly the battery life is awful BUT does it really matter when it sells for $ 80 in Kenya and for 8300 rupees in India ?
To us, not really because we believe that these are small issues compared to improving the lives of thousands of people and enabling a faster diffusion of mobile health to save lives.
Sensaris will release new mobile health solutions for diabetes management and for maternal, newborn child health in the near future with a particular focus on these new platforms for emerging countries.
