Near-Zero Power Required for Temperature Sensor
The ultimate success of wearable Health Tech devices depends in large part on their ability to do more using less power. Better batteries can help device run longer between charges, such as the ARC Centre of Excellence for Electromaterials Science work with biodegradable silk batteries and MIT spinoff 24M's use of colloidal suspension of particles in battery design. The real … [Read more...]
