I have recently worked on a number of Bluetooth devices. For all these projects I have only designed the electronics and PCB. I have not implemented the enclosures, firmware or phone applications. Here are some examples:
This device is a wearable, comfortable, unobtrusive and compact physiological monitoring device that incorporates ECG, accelerometer and body temperature sensors.
This is a discreet biosensing patch that measures your heart and breath. Lief teaches you to control your body's natural stress response through gentle, safe biofeedback exercises. Reduce triggered responses and keep mindful and in control throughout your day.
This device can wirelessly record the frequency
Handwashing at sinks,
Gloves and aprons dispensed
Hand gel usage
It runs on two small AAA batteries that can last about 3 months by using an ultra low current proximity sensor
The system will be used to log airbag pressures for a minimum of 12 hours at 500 Hz frequency, and use wireless to relay this information to a smartphone app for exporting via email. The system will also monitor acceleration and rotation via an accelerometer and gyroscope
This is device is based around the ESP8266
This module allows remote control of the camera via a Bluetooth interface.
A device to weigh bottles and read the NFC code on the base.
One device situated at the start line, and multiple devices down the track with IR beams to detect when the athlete passes each point. By recording their split and finish times the system can be used to analyze and improve performance.
The smart baby pacifier is unique in that it records a baby's temperature and passes it to a parent's smartphone where it can be tracked and medication recorded.
The ability to plot the effect medication has on temperature is particularly useful - no more scrambling for a pen and paper or trying to remember in your head. With useful reminders and alerts it becomes a peace of mind at stressful times.
It comes with a range of other useful features, such as the ability to find the pacifier with your smartphone as well as a proximity feature that alerts your smartphone if the pacifier moves away from you.
This is a sophisticated temperature, humidity and barometric pressure smartphone-based environment monitor that can be used in a wide variety of scenarios - from hotels and guest accommodation and a baby's nursery through to businesses that need to monitor cooled produce and owners of exotic pets.
