Maker Health had some projects on display at the recent World Maker Faire. They describe themselves as:

At MakerHealth we believe in democratizing the tools of health making around the world. Whether it’s a hospital bed, smart pill bottle, or an improved triage mobile phone app we believe that design should be transparent, hackable, and enabling for everyone to be the designers and makers of their own healthcare solutions.

Two of the projects they showed included this pressure sensor which displays the applied pressure to the pad on the OLED FeatherWing add-on:

Also on display was this Smart Spirometer, a device used to monitor air flow into and out of a patient’s lungs – used to diagnose symptoms such as asthma or chronic obstructive pulmonary disease:

You can see the spirometer mounts into the base; the tabs around the edge (seen better below) swivel around and hold the spirometer in place. The VCNL4010 proximity sensor knows when the spirometer is or is not in place and if not, the device can activate a range of notification modules (light, or sound, or vibration) to notify the patient to initiate their spirometry test.
