Engineers at Tufts University have created tiny #sensors that attach to teeth. It’s not a fashion statement, though it could very well someday become one. Instead, the wireless sensors are designed to monitor health and dietary habits, relaying data about sugar, salt, and alcohol intake to a wearer’s mobile device. It’s like a little nutritionist in your mouth that keeps tabs on every time you cheat on your diet.

Technology developed at MIT can harness temperature fluctuations of many kinds to produce electricity
Thermoelectric devices, which can generate power when one side of the device is a different temperature from the other, have been the subject of much research in recent years. Now, a team at MIT has come up with a novel way to convert temperature fluctuations into electrical power. Instead of requiring two different temperature inputs at the same time, the new system takes advantage of the swings in ambient temperature that occur during the day-night cycle.
The new system, called a thermal resonator, could enable continuous, years-long operation of remote sensing systems, for example, without requiring other power sources or batteries, the researchers say.

Arm has a vision of a trillion connected devices by 2035, and each of these devices will need a secure identity, enabling stakeholders to establish trust – for example, allowing a service provider to trust its device base so it can authenticate devices, provide value added services and if needed, issue security updates.

Although low-power RF is the link generally used to initiate a “wakeup” signal to quiescent IoT devices, Stanford researchers developed an IC alternative based on 57-kHz ultrasound.

Good luck saying ‘Sorry I’m late, I had to update my car’s firmware’
“The IETF has noticed how badly Internet of Things firmware is managed, and wants it fixed. The Software Updates for Internet of Things (SUIT) working group was chartered in December 2017 and given the job of fixing this.”

Nano-manufacturing Hub for smart materials and self-powered electronics:
The Engineering and Physical Sciences Research Council (EPSRC) has awarded £1.6m to the Advanced Technology Institute (ATI) and the 5G Innovation Centre (5GIC) at the University of Surrey to establish a hub that will make the manufacturing of smart materials and self-powered electronics a reality in the UK.
The £4.2m project, supported by 32 partner organisations, was co-developed with QinetiQ and the National Physical Laboratory (NPL).

Over 422 million people suffer from diabetes. By 2040 this number is expected to rise to 642 million.
Sweden-based company Brighter was launched in order to provide services and solutions that facilitate self-care and self-monitoring for patients to help them manage their diabetes better.
Brighter has developed Actiste – a connected device that gathers personal health data from diabetes patients and shares it with their caregivers, enabling patients to better manage their condition and caregivers to monitor and personalise their treatment more accurately.
