Biofuel cell tattoo turns perspiration to power generation Wearable biosensors can monitor the human body, but in order to be effective they need portable power. To avoid the need for batteries a Californian team has created a biofuel cell tattoo that can scavenge energy from sweat to generate electricity. |
