We have prosthetic arms and legs to help people who have lost limbs. We have cochlear implants to help people who have lost their hearing. Technology has come up with answers for many different types of physical impairments. Yet one area in particular remains difficult to solve: lost vision. We've covered research that hopes to provide digital technology devices to restore … [Read more...]
Low-Power Chip to Help Wearables Hear
If you're a long-time reader of Health Tech Insider, you know that one of my favorite topics is the user interface for wearable Health Tech devices. While there's no one solution, some approaches have clear limitations. For example, you can't fit a full keyboard on your wrist (at least, not one that is practical to use). Most wearable displays are too small to be used as a … [Read more...]
Green Tea May Provide Flexible Power for Wearables
Most wearable Health Tech devices depend on electricity to power their digital electronics for sensors, data storage, processing, and transmission. And in almost all cases, this means a battery. The problem is that most batteries are hard and rigid, which wearables need to be flexible and softer. Another problem with batteries: they can take a long time to recharge. But a … [Read more...]
Switching Chip Uses No Standby Power [video]
![Switching Chip Uses No Standby Power [video]](http://healthtechinsider.com/wp-content/uploads/sites/9/2017/02/Zero-power-sensor-switch-150x150.jpg)
Digital wearable Health Tech devices require power, and this usually takes the form of electricity. Some devices can harvest the energy that they need from their surroundings, using heat, motion, light, or even radio frequency (RF) waves, but most devices use some sort of battery storage. One key design goal is to make the device run as long as possible on the energy stored in … [Read more...]
Stomach Acid to Power Smart Ingestibles
Digital electronic Health Tech devices require a source of power in order to collect data and communicate it to other devices so that it can be put to practical use. When these devices are worn outside the body, it can be a relatively simple matter to change batteries or plug the device in to recharge it. But what about something that you swallow? Many battery technologies rely … [Read more...]
