AutoDepth by Swift Medical uses a phone’s camera to understand a wound’s depth and severity. Algorithms process dynamic changes over time. Depth can indicate whether a wound is healing properly.
The system is noninvasive, and can be widely accessible to clinicians. In addition to gauging the wound healing process, it can be used for measuring the progression of pressure ulcers, or in the analysis of moles on the skin, where volume, depth, and surface texture are considered.

MIT’s Xuanhe Zhao has designed a bandage that releases medicine in response to changes in skin temperature. It can be programmed to light if wound attention is required, such as when medicine is low.
The flexible, gel-like material incorporates temperature sensors, LED lights, other electronics, and tiny, drug-delivering reservoirs and channels.
Zhao believes that hydrogel coated electronics will also be able to be used inside the body. He suggested that implanted, biocompatible glucose sensors, or soft, compliant neural probes could be created.

MIO and Beneufit have partnered to develop wearables to target the symptoms of Parkinson’s disease.
The pdFIT exercise app was developed to improve manual dexterity and fitness levels in Parkinson’s patients. The wearable continuously monitors progress via sensors on the wrist.
The company claims that its Optimal Heart Rate technology cancels noise caused by movement, due to an added accelerometer. This improves the accuracy of the heart rate monitoring algorithm.

University of Manchester researchers are using electrical stimulation to accelerate wound healing. This can be particularly useful for lower limb venous and diabetic ulcers, and for those with compromised immune systems.
In a recent study, 1/2 centimeter sized superficial wounds were created on the upper arm of 40 volunteers. One wound was left to heal normally, while the other was treated with electrical pulses for two weeks. These pulses stimulated the angiogenesis process, increasing the blood flow to the damaged area. The result was significantly faster healing.
Ardeshir Bayat and Oxford BioElectronics are now developing devices and dressings based on this technology. They will stimulate the nervous system to generate nerve impulses to the site of skin repair.
